	Uh.

	Why are you yelling at PSI when you have failed to do your
own calculations?  Perhaps they have taken data from
archive.route-views.org to determine what the actual loss of
connectivity was.

	I don't have the time to go out and validate the PSINet claims
of how much of the net is gone for them and their (single-homed)
customers.

	Perhaps someone who is more of a data processing person can go
out and provide some interesting data, such as

Number of ASNs single-homed (based on route-views data)
Top 5/10/20/25 providers based on as-path
Number of networks/ips/ASNs behind each of those top 5/10/20/25 that
	would be missing connectivity.

	- Jared
