Apparently on March 22nd from 8 AM until noon eastern time Blackberry service across North America will be going down.
Database upgrades are being blamed and of course on the Saturday of a long weekend is either the best time or the worst time for this but sometimes you have to have these outages to improve services.
The outage has been planned by RIM but of course it is not very easy to alert all users worldwide when this is going to happen. Hope my heads up puts you at a little more piece of mind.
