I know that MFN/AboveNet is quite willing to provide temporary
peering/transit services in the US and Europe for networks affected
by this action.  I suspect most other providers are offering similar
help.  I would hope that the Internet community could get these
networks back online in fairly short order to help keep communications
flowing.  For those networks completely offline, can those with
phone contacts pass this message along to them via voice lines?


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.
