Yeah, well, last week I got the machine rebooted with a static route to
the Real World.
Destination        Gateway            Flags     Refs     Use     Netif
Expire

Just a few minutes ago, it decided to pull the same stunt, becoming
invisible to part of the world, while being reachable from other parts.
There's no messages about anything like this anywhere in the logs or dmesg
output.

I have to wonder about this `Use' figure, what with having been up almost
a week now,
Name  Mtu   Network       Address            Ipkts Ierrs    Opkts Oerrs  Coll

The local netwerk is reachable, as are some remote hosts on the other side
of the default gateway:
traceroute to nimloth.ics.muni.cz (147.251.6.16), 30 hops max, 40 byte

While certain other sites which had access a few minutes earlier are
unreachable:

Naturally, from one of these outside machines, the target machine appears
not to be there:

I might try very carefully ifconfig'ing the interface down and back up to
see if that helps, or manually deleting and adding the default route, but
something tells me that even with a static route like this, I shouldn't be
seeing this.

Again, this is a -current snap from early August, to be updated Real Soon
Now, maybe.
