The problem turned out to be a bad arp entry in the router at the
colocation site. The ip address of the problem machine had been used as
an ip alias on another server a couple years ago to test something, long
before my time here, and whoever set it up neglected to remove its
configuration.

We were decommissioning that machine last night, and apparently it was
rebooted prior to shutting it down and pulling it out of the rack, just
long enough to corrupt the router's arp table.
