Although this sounds high, it is actually low by industry standards, especially for a large site like Twitter with so many resources at its disposal.

The 0.83% downtime figure equates to 5 hours and 43 minutes of lost Tweeting. Network configuration issues as well as spikes of traffic due to the World Cup and NBA Finals caused the downtime.

Unfortunately, Twitter fanatics will not be able to get the lost time back. Maybe the site will have better uptime this month?

99% Uptime Guarantee https://www.internetblog.org.uk/post/1363/99-uptime-guarantee/ Wed, 26 May 2010 14:52:49 +0000 http://www.internetblog.org.uk/post/1362/99-uptime-guarantee/ Billboard saying Guaranteed Rate
It seems as though nearly all web hosting providers promise 99% uptime. Therefore, the promise alone does not make the choice any easier. While there are sites that provide monitoring services that rate the actual uptime of hosts, the real question you should ask a web host is what the guarantee entails.

There is no question that even the best web host will have some down time. That is why no host promises 100% uptime. When your server does go down, what are the consequences? Will the web host say nothing and just eventually turn it back on, pretending like nothing happened? Will they apologize after a reboot? Will they assure you that it will never happen again?

The truth is, when a website is critical to an organization or business, a web host, which is also a business, should compensate the customer for downtime. That guarantee should include a clause about compensation. It may take the form of pro-rating a monthly fee or some other form, but the ultimate outcome should satisfy the customer.

Why uptime matters https://www.internetblog.org.uk/post/1160/why-uptime-matters/ Thu, 01 Apr 2010 10:34:02 +0000 http://www.internetblog.org.uk/post/1160/why-uptime-matters/ rackmount server
Ever notice that most hosts have 99.9% uptime. There’s a good reason why they try so hard to keep things running. While a few percentage points might not seem like a big deal, over the course of a year they can really add up. Just take a look at the numbers:

99.9% uptime= 8.76 hours of downtime
99.5% uptime= 43.8 hours
99.0% uptime= 87.6 hours
97% uptime= 262.8 hours

Even a host that has 99.5% uptime still experiences 2 days of downtime per year! For some, that may not be a problem. But keep in mind that falling uptime figures are a very slippery slope. A seemingly decent up-time of 97% translate to outage time of 262.8 hours, or a little under 11 days.

System monitoring with phpSysInfo https://www.internetblog.org.uk/post/832/system-monitoring-with-phpsysinfo/ Tue, 29 Dec 2009 19:38:08 +0000 http://www.internetblog.org.uk/post/832/system-monitoring-with-phpsysinfo/ phpSysInfo screenshot
Sometimes you just need quick information about your server without having to click through numerous control panel screens or logging via SSH. A small PHP software application, called phpSysInfo, allows you to do just that. Installed like a normal PHP script, you can access a plethora of information about your server, including:

Hostname, Listening IP, Kernel version, Distribution name, Uptime, Current number of users, Load averages, Processors, Devices, Memory, Filesystems, Network usage, and Information about running processes. All of this is presented in a user-friendly graphical format that has a changeable theme.

phpSysInfo is available for Linux, BSD, Winows, OS X, and all UNIX-like operating systems. It is completely web-based and is free software, releated under the GNU GPL. You can download it from sourceforge.net free of charge.

Quick System Information with "Uptime" https://www.internetblog.org.uk/post/641/quick-system-information-with-uptime/ Wed, 04 Nov 2009 16:45:07 +0000 http://www.internetblog.org.uk/post/641/quick-system-information-with-uptime/ uptime
There are several ways to monitor your Linux dedicated server. Some involve typing simple commands, while more advanced techniques require you to study log files. Few, however, are as easy as typing “uptime”. Once entered, you will know a number of things:

1. The system time. Sometimes you might find that your server is running in a different time zone than your home/office computer, which is very important to note.

2. How long your system as been running (may web hosting providers promise 99% uptime, so you should often see an accumulation of days rather than just hours).

3. Number of users currently logged in. Unless you allow users to login via SSH, there should usually only be one: you. This is a quick way to find out if someone might be gaining illegal access to your server.

4. Load average. These three numbers indicated the amount of stress or load on your CPU. The first number shows the last minute, the second the last 5 minutes, and the third the last 15 minutes. Lower numbers are better, so very high numbers may indicate a problem.

With such a simple command, you can find out all of that information and then make decisions about whether you need to investigate further.

Save time with remote reboot https://www.internetblog.org.uk/post/550/save-time-with-remote-reboot/ Tue, 06 Oct 2009 13:11:56 +0000 http://www.internetblog.org.uk/post/549/save-time-with-remote-reboot/ remote control
Last week you learned how a routine server reboot can be a costly affair at some dedicated hosts. Even for those of us with more endearing hosts that do not charge for restarts, the process can sometimes take a bit longer than it should.

Instead of contacting your provider every time you need a reboot, why not utilize remote reboot? This feature, offered by an ever-increasing number of hosts, allows you to reboot the system yourself remotely via the web in the event something goes awry.

The cost is generally minimal: either nothing at all or a few pounds per month. If you value uptime or reboot your server frequently, such a service is invaluable.

Choosing the best host for your money https://www.internetblog.org.uk/post/538/choosing-the-best-host-for-your-money/ Thu, 01 Oct 2009 18:21:54 +0000 http://www.internetblog.org.uk/post/537/choosing-the-best-host-for-your-money/ Graph
Question: How do I choose an inexpensive but reliable web hosting provider?

Answer: Fortunately, there are boatload of people with your dilemma. Some of them have created websites that specialize in rating and reviewing hosts. You can also check the web host uptime to make sure they deliver on their promises.

Another important aspect to consider is the services offered. A web host might offer 99.999% uptime and amazingly low prices but might not have the services you need. Will you need shared SSL and SSH access? Do you want a certain operating system, control panel, or quick installation of certain applications? These are all points to think about when making what will hopefully be a long-term decision.

Finally, it does not hurt to look up the business you are going to pay for service, especially if you are about to enter a year-long deal. Investigate their business practices and claims against them. A web host that might look 100% legitimate may not even be in the country you think it is in. Do not be afraid to ask the tough questions either. In the end you are the customer, and the customer should be completely satisfied.

Choosing a backup solution for your dedicated server https://www.internetblog.org.uk/post/511/choosing-a-backup-solution-for-your-dedicated-server/ Wed, 23 Sep 2009 19:56:36 +0000 http://www.internetblog.org.uk/post/511/choosing-a-backup-solution-for-your-dedicated-server/ Servers

Question: I am looking for a backup solution for my dedicated server. What are my options?

Answer: There are three common options that dedicated server managers typically use. All of them have their benefits and drawbacks.

1. Web hosting company. Often times,the company that owns and houses your server also offers remote backup servers at an additional price. The benefits are that you generally do not have to maintain the backup server, although you may have to do some minor setup to prepare it for backup. You also can depend on the established uptime and reliability of your web hosting provider.

There are a few drawbacks. They will most likely charge a monthly fee for the service, which can add significant cost, depending on the disk space and features you need. You will also have to keep your backup server secure and manage it yourself. And the most significant drawback is that, if something goes horribly wrong with your web host, you could lose both your server and its backup.

2. Third-party provider. There are many commercial backup services available. This gives you the benefit of shopping around for the best prices and features. You also can be sure that if some freak of nature destroys your data center and all the servers in it, your backups will survive.

The downside to this is again the fees involved and the fact that you are putting your trust in a third party after you have already reluctantly offered your trust to your web host.

3. In-house server. “In-house” does not necessarily mean a basement in someone’s home. You could house your backup server in your business office. The benefits are full control over the server, the reliability of your own staff (or yourself) to maintain it, and the lower cost of keeping it running (bandwidth will not be much of a problem since transfers only occur when files are backed up). The drawbacks are that you might not have the same expertise of backup management, thus making the backup files less reliable. You also will not have the data center-level security or power-failure backup.

Research all of the options and decide which one is best for you or your organization. When the day you hope never comes finally does arrive, you will be ready and can rest at ease knowing you have a reliable backup.

Track website outages with uptime monitors https://www.internetblog.org.uk/post/476/track-website-outages-with-uptime-monitors/ Thu, 10 Sep 2009 19:43:43 +0000 http://www.internetblog.org.uk/post/476/track-website-outages-with-uptime-monitors/ server uptime
In the busy world we live in, it’s impossible for most people to monitor their sites 24/7. But tracking your site’s speed and uptime throughout the day is critical. Thankfully, you can use an uptime monitor to track the availability of any URL.

Most uptime trackers charge a small fee per month, but can record when a site goes down, for how long, and also send out a text message or email to alert you of any problems. Some even track website speed.

An uptime monitor can be a good investment in a number of situations. Most notably, the sooner you know your website has a problem, the sooner you can contact your host and get it fixed. Downtime costs money, and the longer your site is down, the more money you lose. Owners of high-revenue or mission-critical sites will find an uptime monitor indispensable.
