Undersea cable cuts in the Red Sea disrupted internet access in parts of Asia and the Middle East, experts said Sunday, though it wasn't immediately clear what caused the incident.
There has been concern about the cables being targeted in a Red Sea campaign by Yemen's Houthi militants, which they describe as an effort to pressure Israel to end its war on Hamas in the Gaza Strip. But the Houthis have denied attacking the lines in the past.
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, The AP news reported.
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.
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.
The lines' cut comes as Yemen's Houthi militants remain locked in a series of attacks targeting Israel over the Israel-Hamas war in the Gaza Strip. Israel has responded with airstrikes, including one that killed top leaders within the Houthi movement.
