It looks like the Microsoft name servers lack any sort of
network diversity. If they had servers in geographically and
network diverse location perhaps this outage would not have
occurred.
Diversity is the best protection against systemic failure.
An important lesson is contained herein.
Agreed, but probably a moot point unless they did the same with the actual
web systems themselves (ie: dns is up, but web servers can't respond due to
DoS).

Maybe this whole DNS outage (unbelievable IMHO)
is just a cover up for their attempt to fix damage
caused by real serious (read: difficult to fix)
problems they have?
