Why Hot Servers are Bad for Your Site

It’s summer time, which means hot weather almost wherever you are. After a harsh winter, many people like the warmer weather that comes this time of year. But the server used to host your website doesn’t like it at all.

Temperature is one of the biggest threats to website uptime. Servers run constantly. The harder they work, the hotter they get, and like any other machine they can begin to break down if they get too hot. The outside temperature may affect them if the data center they are hosted in is not properly cooled.

Heating and cooling in a data center is especially tricky, though. If treated properly, servers are set up to not overheat, but that means more than just cranking up the air conditioning. Data centers use raised floors, so cool air can run underneath and all around servers. Cold water is also pumped in to help cool floors and lower the overall air temperature.

Servers are also spaced out to stop them from overheating one another. Data centers operators go to great lengths to keep these servers at the right temperature. An overheated server will not only stop running in the short term, but could damage hardware or data storage that would be tough, if not impossible, to recover.

What You Should Know

When picking a web hosting provider, ask about the heating and cooling techniques the company uses in its facility. Does it have redundant cooling in case electricity goes out during the hot times of the year? Is there redundant water? What temperature if their facility normally held at?

Knowing these answers will help prepare you. While you will likely never see the server your website is hosted on, it’s good to understand the different types of factors that go into keeping it, and your site, operational. A hot server is a broken server.
