I don't have a breakout of individual networks, so I can't give you
contact information for the networks offline.  I've just been following
total networks, ASNs, etc.  In particular Geoff's great graphs

http://www.telstra.net/ops/bgp/bgp-active.html

It appears a few hundred route announcements disappeared from the total
of 104,400 routes.  In other words, less that 1% of the routes.

Telstra may be located on the other side of the globe, but I'll take
data where I can find it.

I can't tell how many are single-homed networks and servers located in
directly impacted area of New York, and how much is due to a combination
of failures in the area affecting both the primary, backup or alternate
facilities.
