[Sampler] Testing driftwood

Tue May 5 13:35:57 EDT 2020

Perhaps traceroute would reveal something interesting? From my home, using
the library's wifi hotspot:

$ traceroute driftwood
traceroute to driftwood (216.235.254.230), 30 hops max, 60 byte packets

$ ping -c1 driftwood
PING driftwood.blu.org (216.235.254.230) 56(84) bytes of data.

Looks like the routing passes through level3.net to get to synoptek.
Perhaps comcast is having problems with level3?

For comparison, here's the route to a google dns server:

$ traceroute 8.8.8.8
