Three Undersea Cables Cuts Cause Significant Disruption in Europe and Asia

CircleID Reporter

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 Réunion 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

[Editor's Note - Dec 21, 2008: The SeaMeWe-4 cable connects 12 countries: Pakistan, Indonesia, Singapore, Malaysia, Bangladesh, India, Sri Lanka, United Arab Emirates, Saudi Arabia, Egypt, Italy and France.]

France Telecom says that it 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.

The "traffic index" is a score from 0 to 100 where 0 is "slow" and 100 is "fast". It is determined by comparing the current response of a ping echo to all previous responses from the same router over the past 7 days. A score of 0 to 100 is then assigned to the current response depending on if this response is better or worse than all previous responses from that router.
