That was why I lost power the last time. The circuit was faulty. The sites were down for about 15 min while they did this. David - I have an admin who looks after the servers.

A guy I know was doing some contract coding work for an ISP/webhost, and was actually needing to work at a terminal within the datacenter's chilly main server room. Suddenly the ISPs chief engineer comes sprinting in, waving his arms around! His cellphone alerts going crazy! "Everything is down! ARGHH Whats happened?!" They look down, and see that this guy had accidentally knocked a cable out behind the terminal while sitting down. Oooops!

Gary: One time that did happen somewhat, the tech was installing a new server and the power cord came unplugged. That was before he had dual power supplies...

Common ones would be: PDU failure, UPS failure, circuit overload. If your server that you host with has one power supply, you will always have a single point of failure. Check that you have 2 power supplies, connected to two circuits, connected to two different UPS systems. Most hosts provide this as part of the their 'business' plans. Even better, get a cluster set up with redunant load balancers, web servers and database servers and separate network connections to your host's core. Regards, Richard. John,
