We're having some local reports about delays resolving odbc.ucas.com.
The problem is undoubtedly the response of "ns-lp.ucas.com", which
seems to be some sort of load balancer, to AAAA queries. I get log
entries from BIND like

Jul 20 14:35:12 koala.csi.cam.ac.uk named[4539]: [ID 873579 daemon.notice]
   DNS format error from 194.80.160.250#53 resolving odbc.ucas.com/AAAA
   for client 127.0.0.1#42869: invalid response

However, I haven't yet been able to work out exactly *what* is wrong
with the response, as demonstrated by dig (say). Any ideas?


FWIW we can't resolve it either. My colleague says that UCAS have broken their DNS in the past as well, though possibly not in the same way.
