This just arrived from my web host:

We will be upgrading the power strips in our racks today which will result in a short period of downtime for all services (ie HTTP, MySQL, Telnet, SSH, FTP, etc…). Your sites and servers should only be down for approximately half an hour. If you have any questions or concerns regarding this upgrade please do not hesitate to contact our Tech Support Team.

Happy DreamHost Power Team

Like 30 minutes is this short, insignificant downtime for the 27,000 web sites they host. Note to Happy DreamHost Power Team, look up Redundancy, and while you’re at it look up moron too.
