Pet peeve time: screaming technical inaccuracies in blog posts do a huge disservice to the root problem being discussed. If you're going to discuss hijacking DNS errors for the purposes of advertising, then please do so - don't call them DNS "error pages" (there are no such things) or refer to them as "404 errors". 404 is an HTTP status code indicating that the requested resource cannot be found. It is in no way related to DNS and, in fact, such an error code cannot be returned without a successful DNS lookup, which means there's no hijacking...

One of the premises of a greener IT is to reduce the number of servers necessary while maintaining performance levels and meeting capacity needs.
Chances are that many of the HTTP requests received that result in a 404 (not found) message are typos, bots, or bad guys attempting to find a way into your web applications. The thing is that the server must respond to these requests, and it often requires some disk I/O to discover the file doesn't exist. That's expensive in terms of resources and can increase the total power consumption of your servers.
If you're finding enough...
