Hey guys,

Got hit by my first semi significant DoS today, about 28 queries per second caused 4 Mbps outbound.

CPU went from 4-6% to 20%. The whole thing went on for about 4-5 hours until I blacklisted the 3 IPs involved.

They requested a massive TXT record that was on a russian server somewhere.

Anyone see something similar?
