[Subsea Cables Parted in Red Sea Again]

In this post for @kentikinc, I utilize our unique datasets (NetFlow, BGP and latency) to analyze the latest round of submarine cable cuts in the Red Sea affecting internet traffic between Europe and Asia.

Subsea Cables Parted in Red Sea Again
In this post, we dig into the impacts from the latest submarine cable cuts in the Red Sea from loss of transit for regional providers to the increase in latency for the major public clouds.

Submarine cable cuts in the Red Sea disrupt connectivity between Europe and Asia.

Latency spikes as traffic is re-routed around the broken cables. @kentik.bsky.social's Cloud Latency Map captures the impacts here:

If Houthi were intentionally involved, you’re right. Even though, rarely, subsea cable vandalism and theft occurred in the past, sub-state/militia would be a new types of actors.

I’d be cautious with the assumption of Houthi intent. 3 cables of the 2024 Red Sea incident (accidental spill-over of missile attack on MV Rubymar) were repaired with explicit support of the Houthi „govt“. www.datacenterdynamics.com/en/news/subs...

Captain and 1st + 2nd mate of EAGLE S are charged with "outrageous destruction and outrageous interference with telecommunications + alternative criminal offenses."*

EAGLE S dragged her anchor for nine hours Dec 2024 in an attack on comms and power infrastructure of Gulf of Finland.

Cables saboteur suspect EAGLE S stopped in international waters 4 hours ago.

2 hours ago she started proceeding slowly north and is now firmly in Finnish territory.

I find it probable she has been arrested by Finnish navy (usually less visible on AIS).

🇫🇮 Finnish prosecutors are now charging the captain and first and second officers of the #EagleS with “aggravated vandalism and aggravated interference with telecommunications and further criminal charges”, says the Deputy Attorney General.

The case will soon be heard in the Helsinki District Court.

Approximately three-quarters of subsea cables in the Northern Hemisphere pass near or through Irish waters, making it a critical nexus for international connectivity.

ℹ️ Confirmed: #Angola has experienced a wide scale disruption to internet connectivity, attributed by operator Angola Cables to a fiber optic cut between the Angonap and Sangano power plants due to roadworks 📈
Graph from NetBlocks showing the network connectivity in Angola, from July 15, 2025, to July 19, 2025. The y-axis represents normalized connectivity, ranging from 0% to 100%, and the x-axis represents the dates. The green line representing Angola's connectivity remains stable at around 100%, with a sharp drop on July 19. The drop in connectivity aligns with an internet disruption due to a fiber optic cut. Total recovery is now visible. The minimum and current connectivity levels are indicated as 24% and 99%, respectively. The chart has a dark background.

Court records (in Danish) from the Danish Maritime and Commercial Court, on the anchor dragging of SAMUS SWAN, in February 2022.

This resulted in a 6 hour blackout of Bornholm and a huge repair bill (5M EUR).
