i am.  looking at some local passive dns data (generated from ISC SIE),
we find the following single bit errors by anchoring some searches at
the known names and addresses of the f-root server.  DNS does not have
its own crc or checksum, it relies on UDP and IP for error detection
(in which it is weak or nonexistant).  i think it's probably time to
formalize the study of bit errors in DNS, and then see if we can make
a sensible mapping between what we observe and what the solar flux is.

because if they're related and we're going to have a strong solar cycle
then everybody's insurance rates are about to go up.
