T-Mobile Sidekick Disaster: Microsoft/Danger’s Servers Crashed, And They Don’t Have A Backup

Quote from Tech Crunch of what happened:
T-Mobile Sidekick users have been suffering
from a major outage all week, and that issue apparently hasn’t been resolved either.
This goes beyond FAIL, face-palm, or any of the other internet memes we’ve come to associate with incompetence. The fact that T-Mobile and/or Microsoft Danger don’t have a redundant backup is simply inexcusable, especially given the fact that the Sidekick is totally reliant on the cloud because it doesn’t store its data locally. Microsoft acquired Danger for $500 million in February 2008.
Still too early to tell what happened. But key lesson learn perhaps is: server do crash, we just don't know when it happened. Hence: fasten your seatbelt, provide an 'air bag' for your data ... do backup your data now, don't wait until major crash (that eat all your data) happen.
