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.


Sean;

  Here is what we have from DC (times are EDT, from
http://www.multicasttech.com/status/index.html )

Tueseday  : 6:00 AM - we saw 11617 ASN & 103978 bgp routes
Tueseday  :12:00 AM - we saw 11597 ASN & 103697 bgp routes
Tueseday  : 6:00 PM - we saw 11583 ASN & 103548 bgp routes
Wednesday : 6:00 AM - we saw 11566 ASN & 103321 bgp routes
Thursday  : 6:00 AM - we saw 11590 ASN & 103447 bgp routes
Friday    : 6:00 AM - we saw 11534 ASN & 103376 bgp routes

This is all the granularity I have, alas.

The Friday drop is due apparently to loosing 25 Broadway.
The Tuesday drop is slower and more complicated - 

Verio dropped 12 ASN by noon. Renater (AS 2200) dropped 32
ASN between noon and 6 PM. Other interesting ones lost 
include

AS     98  ROCKEFELLER-AS  
AS   4190  BINGHAMTON-U  
AS  11872  SYRACUSE-UNIVERSITY 
AS  13619  BASELINEFINANCIALWTC (a sad AS name now).
AS  17087  NYSA 
AS  19072  OFFICEMAX    
AS  19073  DIGITRADE  
AS  19755  KIMBANET   

Some of these may have lost peering, some, such as AS 13619 and
17087, may have been taken out entirely.
