ISC have issued the BIND advisory
http://www.isc.org/software/bind/advisories/cve-2011-4313
It concerns a bug, thought to be a remotely exploitable, that crashes recursive nameservers, and they have provided new BIND versions (9.4-ESV-R5-P1, 9.6-ESV-R5-P1, 9.7.4-P1, 9.8.1-P1) which are proof against crashing from this cause, although the precise sequence of events that leads to it remains obscure.
Although we are not aware of any local nameservers that have been affected by this problem, several other sites have been badly affected in the last 24 hours.
The CUDN central recursive nameservers at 131.111.8.42 & 131.111.12.20 are now running BIND 9.8.1-P1.
