Redirect to offsite server during downtime

[pgentoo]

killburn,

In my scenario, the whole power at my facility was down for some time. Another example would be long network connectivity interuption.

What i was suggesting is that if you have your secondary nameserver and maintenance page web server in a different physical location (different provider, different building, preferably geographically separate), so there is still something connected and ready to serve DNS/Web requests.

In this case, you could just go to the secondary nameserver, and flip the bind config, so it starts resolving to your maintenance pages (itself for example) until the issues have passed, then flip back to normal.
