In a perfect world your website would be available all day, every day, completely without fail. In reality, downtime happens. Hosting providers like to guarantee uptime, but what does that really mean? Here are three things your hosting provider isn’t telling you about 100% uptime:
#1 - Uptime is your responsibility, too.
When you talk about uptime, you mean that your site is available to your audience. When a hosting provider talks about uptime, they mean network uptime, and possibly hardware availability if you are using shared resources instead of dedicated servers.
In a dedicated hosting environment, device availability and fault tolerance are your responsibility. If a hard drive fails, did you purchase a RAID configuration to protect yourself? Did you elect to build out a database cluster? Redundant firewalls?
Application availability is also affected by your developers. In many cases, changing a single file can drop your site off the radar, even though the pipes are live and the hardware is functional. Do you have a separate development area to prevent this kind of thing from happening? What controls do you have in place to make sure that only stable edits are pushed live?
