Something I've never seen before: Google Server Error 502

I was surprised on February 1, to encounter a Google server error while connecting to blogger.com. I use Google daily and this is the first time I've seen such an outage.
There was news story on a UK website about an the outage.

1 February 2007 - Google's American news service news.google.com appeared to go down this afternoon presenting visitors to the site with nothing more than a 502 error.

The problem cleared up for me in about half an hour.

I expect there will be mainstream news stories about this apparent chink in Google's perceived perfection.

Have you seen this before?

Chuck
