What's up with Blogger?

Up until last week, I could use either Internet Explorer or Firefox to log in to Blogger. Now only Firefox works. Who's minding the ship at Blogger HQ? Neither IE 6 nor 7 works, on neither of my computers, even after following Blogger's instructions. I didn't change anything on my end, it was all on Blogger's side. Don't they have people who, you know, test these things before they make changes?
