disconnected autonomous systems

[Ralph Doncaster <ralph () istop com>]

I've found there are many providers that have completely disconnected
autonomous systems.  For example Yipes (6517) uses L3 on the west coast
and Williams on the east coast.
66.7.129.0/24 is advertised under their AS through WCG and
209.213.209.0/24 is advertised under their AS through L3.

And the number of connected autonomous systems with de-aggregated
prefixes appears to be even more common than a disconnected AS.

It would seem that many (most?) network operators are just ignoring the
more vocal opinions on NANOG.
