Oh, I'm sure there's some brain-dead ISP or BofH somewhere who blocks
traffic to outside DNS servers.  Inevitably it's done in the name of
security.

Even if 8.8.8.8 is reachable, there may be internal, locally defined
hostnames that Google won't know about.

That said, after problems with various DNS servers on various
networks, I usually default to using 8.8.8.8...
