Very strange. If you try to view Wigblog right now the entire blog is inaccessible:
You don't have permission to access / on this server.
The management interface shows all my old posts, but if I republish, I get other errors, and the blog is still down. My guess is they had a disk disaster or a software failure. Makes you wonder if you should back your blog up regularly. I saw signs that Pyra Labs, who created Blogger, were pretty flaky in their technology. You'd like to assume that belonging to Google implies unbreakable tech.
Super Bowl Update:
Wigblog is back. Whatever burped must've gotten fixed.
