[unisog] DNS troubles

We're starting to have problems this week with off-campus folks seeing temporary
inability to resolve some of our servers. Duration of the outage is half an hour
to an hour or two, as far as we can tell. Limited testing suggests that pointing
 to different name servers can fix the problem, sometimes not. At least Verizon
and Cox customers have been affected.

We'd like to rule out our own gear, firewall, packetshaper, etc. before we go
blaming the ISPs. But is anyone else seeing DNS troubles with off-campus users?
Is cache poisoning on the increase this week? Many thanks for your consideration.
