cloudbackup2002.codfw.wmnet paged and then recovered twice for loss of ping at Sun Nov 15 05:27:35 UTC 2020 and Sun Nov 15 05:39:03 UTC 2020. The host reported that it had not rebooted (uptime 362 days).
However, in dmesg:

That would seem like a strange time of day for anyone to bump a cable, so it seems like the network cable might be loose or something.
