Are we thinking its going to get worse??
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. re: ;; matches for IP = 192.5.5.241 (resource records) m.root-servers.net.
