BlackBerry Service down throughout North America -- again

According to the Huffington Post, BlackBerry service is out throughout most of North America. This is the second outage in the last 10 months and in my opinion, reflects a fundamental flaw in Research In Motion's (RIM's) service strategy. If you want a service to work reliably Anywhere, you can't run every single network connection through a single point of failure. Yet, RIM's network architecture routes every single Blackberry connection through its Network Operating Center in Waterloo. People may claim that Apple's iPhones aren't ready for enterprise use, but at least they don't all stop working when Cupertino has a problem. One big outage is an accident. Two is a design problem. And it's time RIM started fixing theirs.
