I think it raises serious questions about RIM's DR strategy if a DB corruption or switch failure or whatever can cause this much outage. 'Surely' RIM have an second site that is independent of the primary (within reason) that they could of flipped to when they realised the DB was borked. If not then any business that relies on them needs to be shouting from the rooftops to get RIM to fix it.
