Another new blog...about Google Data APIs.(used in GCal API, Blogger API, and Base API)
http://googledataapis.blogspot.com/

Currently just gives me an "Internal Server Error 500"

Where did you find this listed, and did it actually show any posts when you looked at it?

All blogspot sites return "Internal Server Error 500", seems very strange indeed..

"Plug it back in! Plug it back in!"

Hmmm, that's not cool – seeing the 500 error in the UK.

mine is working fine (maybe they are changing things to allow us to move to the beta version?)

Well it was working fine, but now i receive a <502 Server Error> .

It's not the first time, unfortunately. Even the Official Google Blog is down.

Even http://status.blogger.com/ is down :)

Maybe it still hav to do with this:

Maintenance on Monday, November 14
We are planning a two hour outage this evening from 9p to 11p (PST). This is to complete the network maintenance we've been performing over the last several weeks.

Update: Completed.

That's from 11/14/2005....

There are loads of sites down – including the official google blog.

Perhaps they're migrating their own blogs to blogger beta. Doubt it, though

It's worth noting that Beta Blogger blogs are loading just fine.
