[dns-operations] GPS time glitch last night

[Mukund Sivaraman]

Some people are reporting a GPS time glitch list night, which seems to
have affected our ntpd instance too. From the logs, it appears to have
stopped trusting GPS clocks due to a greater than expected change in
$GPRMC time. A restart of the ntpd process fixed it.

If you are running a validating resolver or signer with local GPS based
time sources, you may want to check synchronization.
