Every alternate web host promises to provide at least 99.9% uptime. However, did you ever wonder what actually uptime is and how you can check the hosting uptime?
In my last article I have discussed about the 20 basic Web Hosting terms you must know about. Uptime & Bandwidth are the most important ones among them. Let’s talk about Uptime first.
What is Uptime in Web Hosting
Uptime is the time measurement of your server’s activeness. It is basically measured in percentage. Usually the web hosting companies ensure 90% plus uptime which means out of 100 days of a server on, 10 days you may face server down.
Uptime guarantee is actually one of the most common hosting myths. Most of the web hosting companies assure you 99% uptime, however no one can provide 100% uptime. Servers may go down due to many reasons like server maintenance, or when your servers get attacked, etc.
Whenever you or your user requests your site from World Wide Web, they request your server to send some data to them, which is we literally download something from the server (pictures or text). During this time the server will be active and is referred to the uptime of a server.
99% of uptime means the server can be down for 1%, for example, if you are hosting your website on a server for a week or so, your server may go down roughly around 2 hours. Or 15 hours a month and 7 days a year.
How to Check Hosting Uptime
There are some web host providers who provide 100% uptime, which means their servers will never go down. Like Google’s servers are always active since I have started using Google, never felt a second that Google’s servers are down. This means they have a better server which can never be brought down by any attacks or they have alternative servers for maintenance time.

There can be situations when your servers are active and your site is down due to some other reasons. This will not count in downtime. It’s probably your fault or your domain registrar or any other mistake for which your server should not be blamed of.
When you check the box that says “I accept your terms and conditions”, you automatically approve an agreement, Server Level Agreement which states that every server should have a certain time for maintenance in a year. Even 100% uptime servers will have this condition included.
Server Level Agreement (SLA) always plays an important role when servers are down without prior intimation. Servers are usually a computer with large storage that runs throughout a year, which will ultimately need some rest. There should be good cooling system and other things to make sure that the servers run perfectly without any problem, but every machine needs some rest at the end, right?
Finally, to conclude, no server has a 100% uptime. There are servers which have 2-3 backup servers to kick in at the time of server down, but still all that server can be brought down by some powerful means of attack. So, be wise and choose your web host carefully.
That’s all about Uptime in Web Hosting. I will discuss about Bandwidth in my next article. Stay tuned till then!
