Why is Hotmail acting so weird?

For the last week or so, I can’t get in. If I do get in, I can’t read my email. If I can read my email, I can’t send emails. On the rare occaisions that I get in with no problems, it won’t let me sign out.

I expected this kind of behavior to correspond with the transistion to 250mb, but that took place a couple of months ago and seemed to go smoothly.

Already discussed.
