There’s a chill in the air, and winter is just around the corner. Time for scarves, hot chocolate, sleigh rides, and Christmas Carols. And, depending on where you live, time to start planning for some pretty nasty blizzards.
Although they might not wreak quite as much havoc as a hurricane, winter storms can be devastating in their own right. Heavy snowfall can cut off roadways and take down power lines. Extreme cold can make it impossible for employees to manage the trek to the workpRead more
In a previous post, we talked a bit about preventative maintenance - about the importance of establishing and following a proper maintenance checklist. Today, I’d like to examine that topic a little more in-depth. See, there’s a pretty well-established guideline related to proper preventative maintenance.
Complying with it can make all the difference in the world.
I’m talking about the 10% rule, which provides what I feel is an excellent rule of thumb for maintenance cycles.Read more
Fire suppression and climate control systems are both essential to effective data center operations. Thing is, they can also represent a significant threat to your facility if they aren’t properly-maintained. Just look at what happened to the Glasgow City Council’s IT systems last year.
Due to the ‘catastrophic failure’ of an air conditioning unit, an unidentified gas was released into the city council’s data center. Though details weren’t released on its composition, it waRead more
Most data center outages are completely preventable, and the result of human error or negligence. While it’s true that there will occasionally be a catastrophe that’s completely out of your control, those are few and far between. Fact is, if your data center goes down, there’s a good chance that you’re the one to blame.
Preventative maintenance. If you’re going to keep things up and running effectively, that’s a term with which you need to be intimately familiar. The probleRead more
Earlier this month, Delta airlines suffered an outage that left passengers grounded worldwide. After blundering through their own systems for a bit, Delta finally stepped forward and announced that the outage was caused by a power failure in a Verizon data center. Yes, you read that right - losing power in a single data center brought down an entire airline.
Baffling, isn’t it?

Malware. DDoS attacks. Inclement weather, hurricanes, tornadoes, and earthquakes. Hardware failure and human error.
In the context of data center operations, a disaster can take many forms - the only common thread is that your systems are brought down, your data is at risk, and your business loses money. And while you can’t outright prevent incidents like these from happening, you can certainly take steps to mitigate them. You can plan for disaster recovery.
Here’s the thing abRead more
I have good news and I have bad news. We’ll start with the good. Data center outages as a whole have grown somewhat less frequent, according to a new report released by The Ponemon Institute.
Unfortunately, they’ve also gotten more expensive, averaging out at around $9,000 per minute. And while UPS failure is still the leading cause, there’s a new source of failure looming just over the horizon - and it’s likely only going to get worse.
Distributed Denial of Service attacksRead more
There are some component failures you can’t necessarily mitigate against. Human error accounts for 22% of all data center outages - a number that has changed little over the past three years. That indicates that either no one’s bothered to make any progress, or that progress simply cannot be made.
As the saying goes, no matter how hard you try to idiot-proof a system, an idiot will eventually find a way to break it.
The simple fact is that people make mistakes. That’s inevitaRead more
For all that human society has progressed, for all that we’ve taken command of our environment, Mother Nature can still crush us with a flick of the wrist. That isn’t to say we haven’t gotten better at predicting - and weathering through - natural disasters. We definitely have.
When Hurricane Sandy struck New York City in 2012, many data centers were taken offline. Many, but not all. Some, like Peer 1 Hosting, managed to survive without even suffering downtime.
They were preRead more
In the event that the grid on which your data center’s based suffers a power loss, you need to ensure you have a backup power plan in place. We certainly needn’t inform you of the consequences if you fail to do so - insane amounts of downtime (which costs, on average, $7900 per minute), lost data, and lost productivity. But hey - you’ve already got backup generators, right?
Every data center worth its salt has them.
Here’s a question, though - are you practicing proper fuRead more
Your UPS is especially important for when the power goes out in your data center - for that brief period between a blackout and the spinning up of your backup generators. But like every other component in your facility, it can be prone to failure if you don’t properly manage it.
And the consequences of that failure can be dire, from power surges damaging essential components to data loss and corruption.
“A lot of people assume that when power is cut from their computer, it shouRead more
Summer’s about more than just beach vacations and late sunsets. The weather outside is heating up - and that means that as a data center operator, it’s your job to ensure that your environmental equipment (air conditioning, especially), is made to beat the heat.
After all, with the average cost of data centers on the rise, downtime has never been pricier. A single minute of disrupted service costs an average of $7,900. And even though only 21% of data center failures are caused byRead more
So, let’s say you’re trying to get a web-server up and running. As far as you can tell, you’ve configured everything more or less correctly - there are no obvious errors in any of your settings, and all your working parts appear to be working as intended. But there’s a problem - a significant one.
For some reason, no matter what you do, cURL can’t seem to connect with your server. And instead of returning a helpful error message that you could potentially use to troubleshoRead more
Tim Mullahy, Managing Director, and Rex Smith, President, participated at the recent Fifth Annual Greater Chicago & Midwest Data Center Summit. Rex was given the opportunity to speak about the advantages of development and investment in emerging and competitive markets, as well, and they both met a number of other operators and support companies and built a number of new relationships. Tim commented. “ It is always beneficial to talk to others that are facing the sRead more

We’ll just be offering up a quick guide today - we’re going to go over a few of the core services and applications in your Windows Server 2012 installation. Newer sysadmins can think of this as something of a primer, while those with a bit more experience can potentially use it as a cheat sheet. Let’s dive right in, shall we?
As the name suggests, this utility provides the autoproxy service in a Windows Server installation. It’s Read more
If you’re running a database that serves as the core of a set of high-availability business apps, then you need to ensure the server running that database has as much uptime as possible. Today, we’re going to talk about how you can do so with Microsoft’s SQL server 2012.
It’s actually easier than you’d think.

Failover clustering has been baked into Microsoft SQL server for many releases, and makes use of a combination of one or more servers across aRead more
It’s always a terrible thing to lose a loved one to a disease - especially one they’ve been fighting for years. But that’s precisely what happened to one Wisconsin woman, a sufferer of Multiple Myeloma, a form of cancer that attacks the body’s plasma cells. She lost a nine-year battle with the illness on November 7, 2014, leaving behind a grieving husband and community.
Determined to keep her memory alive, they together resolved to plant a field of sunflowers.Today, that field,Read more

Hey there, folks! Today, we’re going to spend a bit of time talking about MySQL, the most popular relational database management system on the web. Now, while it certainly didn’t get where it is by being either obtuse or difficult to use, it can be a bit finicky sometimes - and there are a few ‘gotchas!’ here and there that can present a challenge to even the most seasoned of administrators.
That’s where we come in. Let’s go over a few useful tRead more
There’s always been some contention over which SQL database tool is superior. Every administrator has their preferences, and every programmer has their own unique way of dealing with code. For that reason, if you ask five different sysadmins which platform they prefer, you’re like to receive five different answers.
Let’s see if we can’t help you come to your own answer.
Today, we’re going to look at some of the major database management systems currently available on the Read more

The never ending debate on raised floor vs solid for data centers
In working with some of our newer clients, we are often asked about our decision to go with a solid “flubber” floor over the traditional raised floor. Because we were building from scratch we had the luxury of making this very important choice.
Recently, since our laundry list of reasons was all too familiar to me, we went looking to see what other thoughts were on this topic and came across Chuck Goolsbee’s SRead more
I’d like to start today’s piece off with a few stories.
Steve works as the IT director at a large financial services firm, which recently decided to retire its legacy systems in favor of newer infrastructure. Together with his department, he begins the long process of migrating business-critical data from the old systems to the new. Unfortunately, during the migration, something goes wrong - a huge swathe of data ends up corrupted.
No big deal, thinks Steve. He searches for the baRead more
Being a sysadmin can be really, really weird.
When you work with people who understand little about your job - and even less about the technology you work with - there’s the tendency for bizarre questions, unusual cases, and downright aggravating conflicts. At least there’s a silver lining to all that: they make for some pretty good stories.
Today, we’re going to look at some of those stories - snippets of them, actually. We’ve compiled a list of some of the weirdest thingsRead more

That was a close one.
The Federal Communications Commission almost kicked sysadmins the nation over square in their collective jaw. Almost - but not quite.
Last week, the FCC rendered a major decision in a months-long debate concerning open-source router firmware. Initially intended to address the issue of RF compliance, an ongoing conversation and a proposed piece of legislation took on far greater significance than the governmental body inteRead more
“I’ve noticed a disturbing trend lately,” writes reddit user mrcrassic on the sysadmin subreddit. “When I was first introduced to the concept of “devops” a few years ago, I thought that these were for people who were good at programming AND good at systems, and wanted to use that knowledge to help pure devs ship builds. Instead, what I saw during my last job search (from June to early October) was a lot of hiring managers thought that "DevOps" == "sysadmin + scripting."
The Internet of Things is now inevitable - are you ready?
For the uninitiated, The Internet of Things, or IoT for short is the phrase used to refer to the growing network of connected devices popping up in our businesses, our homes, and our lives. These devices, traditionally ‘dumb’ and not connected to the Internet, are embedded with computer chips to make them more useful, more powerful, and more profitable. Mind you, IoT still has a ways to go before it becomes truly widespreadRead more
Analytics has come a long way in the last couple of years. With the advent of unstructured data - and the tools necessary to analyze it - businesses have the potential to gain insights greater than ever before. This is particularly evident in marketing.

Another day, another executive lodging their own foot firmly in their throat. This time, the party responsible for the PR faux-pas is none other than Oracle’s own Chief Security Officer, Mary Ann Davidson. In a blog post that Oracle’s already taken down and apologized for, Davidson absolutely lambasted the camp of developers who dared reverse-engineer the code in Oracle’s products.
She also rambled on about writing murder mysteries, for some reason.Read more

SSDP - Simple Service Discovery Protocol, also known as Universal Plug and Play - is a process that allows systems and devices to discover neighbors by searching the network, broadcasting their presence, or both. Unfortunately, it was discovered in 2014 that SSDP is actually fairly vulnerable.
The problem, reads a post on the Nexusguard Blog, is that SSDP was never was never designed for the Internet. It was never supposed to be an Internet standard. The fact that it is makes it easily eRead more
If you open the resource monitor in Windows during periods of particularly high memory usage, you might notice something a little disconcerting - the majority of your system memory appears to be allocated to “standby memory.” Generally, this isn’t something you need to worry about - standby memory is simply cached data that Windows will release when another app requires it.
Now, there’s a caveat to this - if you’re frequently receiving “low memory” warnings when the majoritRead more
What Exactly Does The Error Mean?
This is something of a niche error, as your server will not use the SMS Agent Host utility unless it has Microsoft SMS deployed. It’s also worth noting that newer versions of this service are referred to as System Center Configurator Manager. Anyway, assuming you’re using Microsoft SMS, the agent may occasionally fail to start on a reboot.
What Could Be Causing It?
According to Microsoft Support, there are a few possible reasons for this error:
What Exactly Does The Error Mean?
Postfix is by default equipped with a number of controls and safeguards to prevent malicious
This error is returned when Postfix user attempts to send an email and it’s rejected by the target domain. It usually means the user isn’t properly authorized - either they’re connecting from a non-trusted domain or they aren’t targeting a trusted destination.
What Could Be Causing It?
Misconfiguration, more often than not, though occasionally DNS isRead more
What Exactly Does The Error Mean?
When a packet is sent, it has a value applied to it called TTL (Time To Live). This value decreases in increments every time the packet ‘hops’ from one network location to another. When it reaches 0, it is automatically dropped, and the time to live exceeded error is returned.
What Could Be Causing It?
The most common cause of this error is a routing loop somewhere in the network, either as a result of misconfiguration or a temporary hiccup in the Read more
Generally speaking, Port 7070 is used for multimedia applications such as Apple Quicktime Streaming Server and RealAudio. Certain games - such as City of Heroes and City of Villains - also make use of the port. It goes without saying that, as a result, you’re not likely to make use of this port on your server.
So what can you do if it appears to be open and shouldn’t be?
There’s a good chance your router is to blame here. Try listening on the port to see if it’s really open - Read more
You can add a bit of extra security to your server by disabling SSH password authentication altogether, and instead using a pre-generated, private key. Note that if you lose said key, you’ll lose remote access to your server. In order to do this, take the following steps:
Open your sshd_config file, and look for the line #PasswordAuthentication. Change the flag from yes to no.
Run the command ssh keygen on your machine to generate a public and private key.
Copy the public key infoRead more

Most hosting firms allocate ‘blocks’ of static IP addresses to their clients, identified by a CIDR notation (such as /29 or /30). Each block represents a particular subnet on the host’s network, and each subnet has its own subnet mask.
In networking, IP addresses consist of two core components: the network address and the host identifier. CIDR notations describe how many bits of the address (there are 32 in total, and each bit can be either 0 or 1) are used for the routing/networkiRead more

What Exactly Does The Error Mean?
Occurring during server configuration, Error 17 signifies a communication failure between the remote connection and the host machine.
What Could Be Causing It?
There are a few factors which could potentially return an error 17 with a connection attempt (via Microsoft):
The server is not running
The SQL server software is incorrectly-configured
Permissions are not properly configured
Port 1433 is blocked, or a firewall is interfering with the Read more

Times have changed. Many businesses, even those outside of the “tech” industry, simply cannot operate without networking hardware in place, particularly in industries such as healthcare and finance. This has been a major driver in the expansion of the data center industry, and in the leasing of optical cables, referred to as dark fiber.
Some of you have probably heard that term before. It’s a buzzword that’s been floating around the hosting space for a while now; one whose defiRead more

It’s tough being the founder of a startup. You’re often holding the weight of an entire business on your shoulders, made heavier by the expectations of shareholders and colleagues alike. No wonder 99% of entrepreneurs end up failing or burning out - for some; the stress, pressure, and long hours are together simply too much to bear.
In light of this, it’s also not surprising that those who do manage to get their startup off the ground might occasionally display the tendency to Read more

As I’m certain you’ve all heard by now, Microsoft intends to make Windows 10, the next iteration of its Windows Operating System, freely available to all users. Pretty big news, though it certainly didn’t come as any surprise to those familiar with the tech industry. The fact is that consumer expectations have changed - and Microsoft’s paid upgrades are simply a relic of an older time.

In a landslide decision in February, the FCC reclassified the Internet as a public service, putting it under the umbrella of Title II regulations. Internet advocates around the world rejoiced: they had finally won a hard-fought legal battle over net neutrality. Cable and Internet providers, they said, would no longer be able to abuse their power to force companies to pay for fast-lane Internet.
The companies attempting to oppose the classification weren’t quitRead more
The Liberty Center One facility was originally built as a light industrial site. It functioned for years as a tool and die shop which provides a solid foundation for some of the heavy duty equipment that we deploy in the electrical infrastructure – our dual UPS system, step down transformers, paralleling switchgear and transfer switches. The solid block construction also contributes the building’s overall integrity. Data centers require a tremendous amount of space for supporting equipRead more
One of the main factors considered by the design team was how we could re-purpose excess power and HVAC resources that were going unused in the active data room. When we planned out the facility 5 years ago, we anticipated that customers would demand rack environments that could support high power densities. And while we have had some customers deploying as much as 19 kW in a single rack, the majority of our customers have had more modest power requirements. The end result is that while Read more
As we progressed with the planning for the new data room expansion, we also looked at changing the traffic patterns in the building. One of the first items on hand was to improve our technicians’ access to the Generator Yard. Previously, we would have to leave the electrical room, walk out into the hallway and then exit into the generator yard through a keyed door to get to the generator yard. The new plan allows us to go directly out to where the generators are from the data room.
Our construction crews have made significant progress in converting our expansion space into a new data room floor, but one of the guiding principles is to keep things clean. In expanding the space, we had to create some new door openings, so before we did anything we created these shrouds show here that was designed to keep dust and debris out of the active spaces in the facility. You’ll see more of these being erected as we move around to other areaas of the building.
As we beginRead more
You have heard us talk about our expansion plans and we are pleased to inform you that we will be swinging hammers very soon.
In the very near future, we are starting on this expansion project which will more than double the floor capacity at Liberty. This expansion will take advantage of our ability to re-deploy untapped power and cooling assets from Data Room A to start services in Data Room B. Essentially, we have two completely dormant PDUs in Data Room A which can be used to populatRead more
I have several stacks of paper in front of me.
In one stack is a series of documents that we are using to do an analysis of the current and potential building electrical load we have today. One document is one we create every month called our power audit. We use it to track circuit loads and to make sure our customers are within the safe zone of their circuits. It also gives us a comparison between actual usage and demand availability. A very important measurement – electrical demandsRead more
We met last Friday with our team at Integrated Design Solutions (ids) and spent several quality hours with their team discussing topics from room dimensions to electrical load projections and everything in between. Lots of great ideas and analysis and we’ll be sharing some of it with you shortly, but one thing that just blew me away was an alternative they present for our flooring. Now flooring is just one of those things taken for granted in the data center. Most everyone is used to seeRead more
Welcome to the Liberty Center One blog. We hope you will look in frequently and participate in the conversation as we take the next step in our plans to expand out into our second room (affectionately known as Data Room B).
Four years ago, Liberty Center One looked like this:.
And from these beginnings we transformed the building to look like:
And now it’s time to transform the facility again.
We’ve been thinking about this step for some time now. As mRead more
What is HA/HD you may ask.
It’s our way of describing two of Liberty’s most important attributes.
HA = High Availability. We've built redundant systems to ensure that our customers enjoy a resilient environment that can withstand power outages, carrier outages, hardware failures, and other types of problems that could potentially take a data center down.
Our original facility design had us using one huge generator per data room. And while having backup generator capacity is extRead more
Liberty Center One was projected to have two data rooms, both of about the same size.
When we bought the building the space designated for the data rooms was a 8,000 square foot, high ceiling warehouse. But, we knew that lighting the total footprint would create major inefficiencies and would also inhibit our ability to make building changes down the road with active production customers in the space. So we built out half the room and left the other half until later.
Well, later is noRead more
