Verio Decides what parts of the internet to drop

Apparently for their convenience Verio has decided what parts of the Internet I
can get to. With no notification. This was (eventually) posted to the BSDI
mailing list when some of us were cut from access to the site we need to
maintain our OS.

For this I pay them.
