MyDoom wave wipes out RoadRunner

There was a big wave of MyDoom this morning, and RoadRunner mail servers stopped responding to SMTP (POP still worked). RoadRunner responded by rebooting the servers, but the problem may have been with their routers, or possibly with their DNS (or they may have problems with these services as well).

We experienced the same symptom as RR on our Epic Alliance mail server - but only when trying to reach it through RoadRunner - from other sites it responded fine.

(Is this off topic? I couldn't decide. RoadRunner used to run Microsoft mail servers. Epic runs some sort of Sun product; I run various servers including Microsoft, RedHat, and Gentoo.)
