BlackBerry services down in North America yet again?

Look, BlackBerrys are always supposed to do a few things well: 1) grab your email in real time off an Exchange server; 2) make you look important; and 3) work. It seems, though, that we're working on our third major North American outage here in less than a month, with reports flowing in that users connected to BIS are having trouble with Messenger, web browsing, and apps that consume data (though email is inexplicably unaffected). Anyone out there seeing problems?
