Internet assessment - September 13 2001

Approximately 5,000 people are still missing in three different areas,
rescue efforts continue in New York City. Recovery efforts are underway
at the Pentagon and southwest Pennsylvania crash sites.

Normal telephone repair activities are still suspended in New York City
and parts of Maryland, Virginia and Washington DC.

Verizon is continuing its repair of 140 West. NYSE is closed Friday, and
plans to conduct a full scale stress test over the weekend, and reopen on

Other than 140 West and the equipment in the World Trade Center, no other
telecommunication CO's have any reported structural problems. Access to
several telecommunication sites in Manhattan is still restricted.

Reports of imminent collapse of other Internet or Telco facilities in
New York City have been false.

AT&T and Earthlink have added additional Internet dialup telephone numbers
in the New York area. Earthlink status pages show many DSL lines in New
York City are still down.

Genuity's web site has a message from its Chairman about the three
people still missing from the Genuity family.

UUNET status page reports they are working under "routine emergency"

Sprint is restoring Sprint PCS service in Manhattan. Four cell sites
were damaged, and other cell sites were cut off due to failures in the
wireline carrier.

RCN, a major regional provider in New York City and Washington DC, status
page reports its service has been restored.

Qwest, Level 3, Williams and other new carriers report no impact on
their networks. hasn't been updated in months. Anyone know a current website
for C&W?

Equinix, Exodus, MFN/PAIX/Abovenet, and other colocation providers
announced they are prepared to assist companies needing to emergency
assistance to relocate Internet operations. See the company's web site
for details on how to contact them if you need such assistance.

Fuel supplies reached 25 Broadway, but the generator shutdown shortly
afterwards due to overtemperature. Telehouse Broadway acts as one of
the US/European exchange points for several regional and mid-level
networks. Based on figures from the NYIIX web site and Abovenet MRTG
graphs, several hundred megabytes of traffic shifted to alternate routes.
The Internet routed around much of the failure, but there seem to be
only a few individual networks which are unreachable. The generator
was restored and then failed again.

Power is still out in lower Manhattan, ConEdision is bringing in additional
generators with the assistance of FEMA. ConEd is also helping some sites
arrange fuel deliveries.

Cisco TAC has created a new priority schedule for replacement parts within
the USA. There are now priority levels above P1 for problems affecting
national security and emergency service (hospital, police) networks.
"Normal" P1 calls and shipment of any replacement parts will be handled
after national security and emergency service networks. Air cargo shipments
are still delayed.

I expect other major router hardware vendors have implemented similar
priority shipping schedules.

Special Note: There have been several hoaxes directed at Internet Service
Providers. ISPs shouldn't make changes based on phone calls allegedly
from police, military or similar sources. Consider using extra care
to verify the source of the information or request.

I found a status page for C&W via which went to

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?

Note that US Federal Law specifies those additional priorities,
so while they are not "normal", all equipment providers are required
to handle national security and emergency services network providers
preferentially -- whenever the special precedence is invoked by an
authorised requestor. AFAIK, this process was last used during the
Gulf War, when DoD sent their own trucks/people to vendors pick up the
network/computer equipment they needed, then flew it out via MAC.
This precedence also applies to new equipment, should any be needed.

        As an aside, the part of the Pentagon hit was using Extreme
Networks' switches/routers for their unclassified networks.
