Ok, this is just getting painful to watch - RIM has managed to have another major outage on their BlackBerry network.  As I'm sure everyone is aware, this isn't the first, second, or third time it's happened.  Heck, I've even posted about the last on here. So here's a snippet from the latest Reuters news posting on the issue:

"A major outage hit BlackBerry users in North America on Monday afternoon, cutting off wireless e-mail for everyone from busy executives to political campaign staff on the eve of three U.S. presidential primaries. The problem, which BlackBerry owner Research In Motion described as a "critical severity outage" affecting users in the Americas, once again raised concerns about the stability of the e-mail service 10 months after a widespread crash last April."

It's worth noting, that this outage doesn't cut off wireless email for everyone - just those that have bought into the centralized NOC design that RIM offers.  If you're using Microsoft's Direct Push then this won't affect you - unless you're trying to email someone that has a BlackBerry device.
