First Story on it so far. Any additional details would be appreciated.

http://www.computerweekly.com/Articles/2008/12/19/234016/cable-damage-disrupts-internet-services.htm
A sub-sea cable carrying more than 75% of traffic between the Middle East, Europe and America has been damaged.

According to news service Bloomberg, internet and telephone communications <http://www.computerweekly.com/Articles/2008/11/17/233425/internet-service-reaches-for-the-stars-through-the-cloud.htm> between the Middle East and Europe have been impacted by submarine cable failures <http://www.bloomberg.com/apps/news?pid=newsarchive&sid=aFM6PQsd6i2Q> between Italy and Egypt in the Mediterranean Sea.

Bettina Tratz-Ryan, research vice-president at Gartner, said, "Personally, I think this is very dramatic." She said that the disruption in network traffic could impact e-commerce sales during the busiest weekend before Christmas. "It will have a substantial impact."

Tratz-Ryan said, "People take network communications <http://www.computerweekly.com/Articles/2008/02/28/229620/firms-must-build-tight-slas-into-virtual-network-comms.htm> for granted, but the underlying network <http://www.computerweekly.com/Articles/2008/12/10/233829/taylor-wessing-improves-network-with-geo-fibre.htm> needs to be secure."

Alex Smith, research analyst at Canalys, said, "These type of problems have happened before. Network connects will be re-routed, but connections will be slower."

Interoute was one of the European telco providers to spot the problem. Jonathan Wright, director of wholesale products of UK ISP Interoute, said, "The potential impact of an outage of this size cannot be underestimated - it is like severing a major artery. In a global economy with financial centres based around the world, and an increasing use of outsourced call centres and IT departments, it is essential that companies are confident in their communications networks."

Three undersea cables cut: traffic greatly disturbed between Europe and
Asia/Near East zone
Paris, December 19, 2008

* 3 cables cut this morning (Sea Me We3 partly + Sea Me We4 + FLAG)
* France Telecom Marine cable ship about to depart


France Telecom observed today that 3 major underwater cables were cut:
"Sea Me We 4" at 7:28am, "Sea Me We3" at 7:33am and FLAG at 8:06am.

The causes of the cut, which is located in the Mediterranean between Sicily
and Tunisia, on sections linking Sicily to Egypt, remain unclear.

Most of the B to B traffic between Europe and Asia is rerouted through the
USA.

Traffic from Europe to Algeria and Tunisia is not affected, but traffic
from Europe to the Near East and Asia is interrupted to a greater or lesser
extent (see country list below).

Part of the internet traffic towards R?union is affected as well as 50%
towards Jordan.

A first appraisal at 7:44 am UTC gave an estimate of the following impact
on the voice traffic (in percentage of out of service capacity):

- - Saudi Arabia: 55% out of service
- - Djibouti: 71% out of service
- - Egypt: 52% out of service
- - United Arab Emirates: 68% out of service
- - India: 82% out of service
- - Lebanon: 16% out of service
- - Malaysia: 42% out of service
- - Maldives: 100% out of service
- - Pakistan: 51% out of service
- - Qatar: 73% out of service
- - Syria: 36% out of service
- - Taiwan: 39% out of service
- - Yemen: 38% out of service
- - Zambia: 62% out of service

France Telecom immediately alerted one of the two maintenance boats based
in the Mediterranean area, the "Raymond Croze". This France Telecom
Marine cable ship based at Seyne-sur-Mer has received its mobilization
order early this afternoon and will cast off tonight at 3:00 am with 20
kilometers spare cable on board. It should be on location on Monday morning
for a relief mission.

Priority will be given to the recovery of the Sea Me We4 cable, then on the
Sea Me We3.

By December 25th, Sea Me We4 could be operating. By December 31st, the
situation should be back to normal.
