Multiple subsea fiber cuts in the Red Sea impacting global communications
Impact Summary
Starting at 05:45 UTC on 06 September 2025, traffic traversing through the Middle East originating and/or terminating in Asia or Europe regions may experience increased latency due to multiple undersea fiber cuts in the Red Sea. The disruption has required rerouting through alternate paths which may lead to higher-than-normal latencies.
This advisory is intended to raise awareness ahead of increased demand as the regions enter the start of its work week.
Current Status
Multiple international subsea cables were cut in the Red Sea. Our engineering teams are actively managing the interruption via diverse capacity and traffic rerouting, while also discussing alternate capacity options and providers in the region.
Undersea fiber cuts can take time to repair, as such we will continuously monitor, rebalance, and optimize routing to reduce customer impact in the meantime. We’ll continue to provide daily updates, or sooner if conditions change.

- cr125rider 1y agoThe smart folks who keep these things running, despite failures like this, are incredible. Hats off to you all, good luck in the coming weeks as you have to deal with this.

- sporkxrocket 1y agoYeah all of the Palestinians that Israel has been holding hostage since well before Oct 7th need to be freed.

- marcosdumay 1y agoYes, but it's damn time people start upgrading to BGP ==3.
- matt-p 1y agoMost likely not. Almost certainly bfd or ldp/mpls

An article about people who fix this Also, the teams are quite busy: > "There are 150 to 200 instances of damage to the global network each year. So if we look at that against 1.4 million km, that's not very many, and for the most part, when this damage happens, it can be repaired relatively quickly." ... > If a fault is found, a repair ship is dispatched. "All these vessels are strategically placed around the world to be 10-12 days from base to port," ... > To repair the damage, the ship deploys a grapnel, or grappling hook, to lift and snip the cable, pulling one loose end up to the surface and reeling it in across the bow with large, motorised drums. The damaged section is then winched into an internal room and analysed for a fault, repaired, tested by sending a signal back to land from the boat, sealed and then attached to a buoy while the process is repeated on the other end of the cable.
- adolph 1y agoI wonder how much slack is left in the cable over its run in order to facilitate bringing it up for repair.
- soupfordummies 1y agoNow that’s what i call a service loop!
- throwup238 1y agoAt first it’s an average of 1% slack across the entire run but up to 5% in rough terrain. They don’t use slack though for repairs, they lay down new cable between the bights that adds up to several miles to the length.
