Based on numerous tips, articles scattered across the internet, and the like, we can confirm that BlackBerry Internet Service (BIS) is down in North America.  Oddly enough, BlackBerry Messenger seems to be working just fine.  No word on when it'll be back up and running again, but it's quite frustrating, to say the least.  I'll update when I receive my e-mails.

As Engadget correctly points out, RIM has suffered two straight months of BIS problems.  With these outages, do you see business users migrating to alternative platforms?
