Nothing odd about it. This is exactly what an NTP node looks like
when it has no contact with the outside.

Everybody who reads here for a week has seen it. Usually, it's
your firewall not allowing NTP traffic, or your broadband modem
getting a new IP address due to DHCP lease expiration. (More
likely the former if restarting NTP does not help; the latter if
it does.)
