Good error pages

When your web presence is down for some reason or if your visitors make a go for a page no longer there, you can basically tell them in two ways: Good or bad.

Netvibes is down today for a server upgrade. Their error page tells it all – the graphic alone is class and the message is clear and friendly.

Bloglines is another one that does it well (I love their plumber :).

Does yours?

(hangs head – knowing that there is no such thing as customized 404 pages on the sites that I webmaster…)
