	I am not certain whether this link is relevant:

	http://www.internetpulse.net/

It indicates congestion on the networks of Cogent and Savvis. AFAICT, 
none of the packets from Verizon cross the network of either of those 
ISP's, Cogent or Savvis.

	This second link is likely even less relevant, but interesting 
nevertheless:

	http://www.noc.ucla.edu/weather.html

	Still less relevant:

	http://www.caida.org/home/
