Indeed. IIRC the spin M$'s PR people put on this fiasco was the
problem had been caused by a malicious external attack. That deflected
people away from the root cause: M$'s appallingly bad DNS set up. Now
it seems this myth about an external attack has taken over from what
really went wrong. There *was* a DoS attack: somebody at M$ was stupid
enough to put all their name servers for microsoft.com behind one
router -- well duh! -- and then somebody else at the company screwed
up the configuration of that single point of failure.
