That facebook poorly managed their DNS to cause the recent disaster
is an important evidence to support my point that DNS, so often, may
not be helpful for network operations against disastrous failures,
including, but not limited to, DNS failures.
I don't want to wade into the middle of this argument, but has there been more information about the recent facebook outage released that I missed? All I've read seems to say that the loss of connectivity to their DNS servers was a symptom, rather than the cause of the outage.
