CNN is reporting that there has been another Blackberry outage. It was less impactful than the last time around, but at least one question remains: Why does Research in Motion (RIM; maker of the Blackberry) funnel all email traffic through their data centres, rather than having it handled by the individual cellular carriers, which (1) would be like most, if not all, other smart phones, and (2) would provide some diversity?

Don't get me wrong: The Blackberry that I've been carrying for a couple of years now at the behest of my employer has been pretty reliable. Even so, it seems that it would be in RIM's interest to spread out their infrastructure a bit, at the very least.
