The DNS entries for the EFnet and other mainline IRC servers previously
affected appear to have timed-out/been removed from various ISP
caching DNS resolvers I checked. I didn't check if all the routing
blackholes have cleared up.
User-based IRC servers should back to being pummled by Bot C&C requests
as normal now.
As I said, false positives suck. Unfortunately there isn't an anti-abuse
system that never makes a mistake; unless you do nothing. I'm skeptical
of people who claim they've never made a mistake.
