Undersea cables cut in the Red Sea, disrupting internet access in Asia and the Mideast

Undersea cables are one of the backbones of the internet, along with satellite connections and land-based cables. Typically, internet service providers have multiple access points and reroute traffic if one fails, though it can slow down access for users.
Microsoft announced via a status website that the Mideast “may experience increased latency due to undersea fiber cuts in the Red Sea.” The Redmond, Washington-based firm did not immediately elaborate, though it said that internet traffic not moving through the Middle East “is not impacted.”
NetBlocks, which monitors internet access, said “a series of subsea cable outages in the Red Sea has degraded internet connectivity in multiple countries,” which it said included India and Pakistan. It blamed “failures affecting the SMW4 and IMEWE cable systems near Jeddah, Saudi Arabia.”
The South East Asia–Middle East–Western Europe 4 cable is run by Tata Communications, part of the Indian conglomerate. The India-Middle East-Western Europe cable is run by another consortium overseen by Alcatel-Lucent. Neither firm did not immediately responded to requests for comment.
Pakistan Telecommunications Co. Ltd., a telecommunication giant in that country, noted that the cuts had taken place in a statement on Saturday.
Saudi Arabia did not immediately acknowledge the disruption and authorities there did not respond to a request for comment.
In the United Arab Emirates, home to Dubai and Abu Dhabi, internet users on the country's state-owned Du and Etisalat networks complained of slower internet speeds. The government did not immediately acknowledge the disruption.
Subsea cables can be cut by anchors dropped from ships, but can also be targeted in attacks. It can take weeks for repairs to be made as a ship and crew must locate themselves over the damaged cable.
