A French team of engineers on board the cable repair ship Raymond Croze have begun to repair the underwater cables that were severed late last week in the Mediterranean. The incident is causing major internet and communication problems for the Middle East and much of India. It is now believed that the lines were cut by European fishermen who were trawling nets off the coast of Sicily.
The cables – Sea Me We 4 (SMW 4), Sea Me We 3 (SMW 3) and FLAG EA – run under the sea between Egypt and Italy and carry 90% of all data between Europe and the Middle East.
Rajesh Chharia, president, Internet Service Providers Association of India, says, “The cables are expected to be down till the end of the month. One of the two maintenance boats in the Mediterranean, the Raymond Croze, a France Telecom marine cable ship, will reach the location on December 21.”
According to a France Telecom report, while Maldives is 100% down, there has been an 82% disruption in India. Among other countries affected are Saudi Arabia, Egypt, UAE, Malaysia, Pakistan, Qatar and Zambia. [Continue Reading →]

Hit hard by the internet crash in 2000 cable laying ships (video) were hard pressed to find contracts laying subsea communication cable and took on less traditional projects like oceanographic research (see video below).
With eight long years behind us and the internet seeing a rebirth in what is called Web 2.0, the impressive cable laying ships are back in business. The SMH writes:
It grabbed the attention of wave riders this morning, but surfers of the web are likely to benefit most from a large ship moored near Sydney’s eastern suburbs beaches.
French vessel Ile De Sein was moored off Tamarama Beach this morning, as part of a project to lay 9000 kilometres of submarine cable between Sydney and Hawaii.
The cable, being laid by telecommunications company Alcatel-Lucent in partnership with Telstra, aims to boost the internet capacity between Australia and the US.
“The explosion of user-generated online content means we need more capacity than ever before with the United States, which is already the destination for two-thirds of all Australian traffic on the internet,” Telstra Wholesale’s Kate McKenzie said.
The cable is expected to be active by the end of the year.
The presence of the large ship so close to shore brought back memories of the Pasha Bulker, the bulk carrier that ran aground on Nobbys Beach, Newcastle, following a storm last year.
But a police spokesman said Ile De Sein had not issued any distress calls this morning. Continue Reading…

Sea-Fever’s Peter Mello submitted the following story to our Maritime News Discoverer;
A flotilla of ships may have been dispatched to reinstate the broken submarine cable that has left the Middle East and India struggling to communicate with the rest of the world, but it took just one vessel to inflict the damage that brought down the internet for millions.
According to reports, the internet blackout, which has left 75 million people with only limited access, was caused by a ship that tried to moor off the coast of Egypt in bad weather on Wednesday. Since then phone and internet traffic has been severely reduced across a huge swath of the region, slashed by as much as 70% in countries including India, Egypt and Dubai.
While tens of millions have been directly affected, the impact of the blackout has spread far wider, with economies across Asia and the Middle East struggling to cope. Governments have also become directly involved, with the Egyptian communications ministry imploring surfers to stay offline so business traffic can take priority. “People who download music and films are going to affect businesses who have more important things to do,” said ministry spokesman Mohammed Taymur.

UPDATE: 2nd Cable Reported Cut
The BBC Tells Us:
The first cable – the Fiber-Optic Link Around the Globe (FLAG) – was cut at 0800 on 30 January, the firm said.

A second cable thought to lie alongside it – SEA-ME-WE 4, or the South East Asia-Middle East-West Europe 4 cable – was also split.
FLAG is a 28,000km (17,400 mile) long submarine communications cable that links Australia and Japan with Europe via India and the Middle East.
SEA-ME-WE 4 is a submarine cable linking South East Asia to Europe via the Indian subcontinent and the Middle East.
The two cable cuts meant that the only cable in service connecting Europe to the Middle East via Egypt was the older Sea-M-We 3 system, according to research firm TeleGeography.
The firm said the cuts reduced the amount of available capacity on the stretch of network between India and Europe by 75% percent.
As a result, carriers in Egypt and the Middle East re-routed their European traffic around the globe, through South East Asia and across the Pacific and Atlantic oceans. Continue Reading…
