Standby Servers
We keep spares on-line of all CPU configurations. If the server were to experience a hardware failure we would literally turn a key, grab the handle on the drive, pull it out, and insert it into an identical standby CPU. We would reboot the second machine and the server would be up and running again in a matter of minutes.
What Does This Mean For You?
It means your website is incredibly secure from failures or downtime. It means your website is up and running as near to 100% of the time as it's conceivably possible to get.
