Everything about Fiber-optic Link Around The Globe totally explainedFiber-Optic Link Around the Globe (FLAG) is a 28,000 kilometer long submarine communications cable containing optical fiber that connects the United Kingdom, Japan, and many places in between. The cable is operated by India's Flag Telecom, a fully-owned subsidiary of Reliance Communications. The system runs from the eastern coast of North America to Japan. Its Europe-Asia segment is the fourth longest cable in the world.
The Europe-Asia segment was laid in the mid-1990s and was the subject of an extensive article in Wired Magazine in December, 1996 by Neal Stephenson. The cable was laid by NYNEX.

January and February 2008 service disruptions
On January 30, 2008 internet services were widely disrupted in the Middle East and in the Indian subcontinent following damage to the SEA-ME-WE 4 and FLAG cables in the Mediterranean Sea. BBC News Online reported 70% disruption in Egypt and 60% disruption in India Problems were reported in Bahrain, Bangladesh, Kuwait, Pakistan, Qatar, Saudi Arabia and United Arab Emirates. The respective contributions of the two cable systems to this blackout is unclear. Network outage graphs suggest that the two breaks occurred at 0430 and 0800 UTC.
The cause of the damage hasn't been declared by either cable operator, but a number of news sources speculate that the damage was caused by a ship's anchor near Alexandria. According to the AFP, the Kuwaiti government attributes the breaks to "weather conditions and maritime traffic." The New York Times reported that the damage occurred to the two systems separately near Alexandria and near Marseilles. Egypt knew of "no passing ships" near Alexandria which has restricted waters.
One day later, on February 1, 2008, the FALCON cable was also reported cut 56 km off Dubai.
