Yet another BlackBerry outage?

We’re hearing a lot of reports that RIM’s BlackBerry network is down again. This isn’t confined to one carrier (we’re on AT&T and ours is a wrap). It looks as if Waterloo has acknowledged the issue, and classified it as a "critical severity outage". Not looking good. Let’s go, readers. Are you down for the count? If so, list your carrier!
