It's been a bit flaky yesterday as well, I couldn't log on when I got up this morning (around 8:30, no classes in the morning today,) but after I got back from Tim Horton's I could (I'd say about half an hour to 45 minutes?) I knew that Messenger was still a little screwed up this morning when it didn't even attempt to log me in when I turned on my notebook. (I have it set to log me in automatically.)
