HNLMS Johan de Witt (L801) and a German naval vessel are operating in the Irish Sea tonight, quite close to where Yantar hovered last November.
German SIGINT vessel OKER is further north, in the Firth of Clyde.
AIS flag hopping for the top 200 worst shadow fleet ships, September to October.
The "pivot to The Gambia" of the shadow fleet is increasing day by day.
But also "pivot to Sierra Leone".
Initially, I thought this was "just" another case of false flagging, unbeknown to the registry.
But something in common about both these nations, causes me to think, that it's not the case.
French military personnel have boarded Russian shadow fleet oil tanker named "Boracay". Vessel is suspected of being a launchpad for drones that forced the closure of airports in Denmark last week.

[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.

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.
🇫🇮 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.

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.
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 📈

Denmark allocates 3.4bn (456m EUR) to satellite-based detection and intelligence gathering to improve situational awareness.
The package includes additional satellite capacity to cover wider geographical areas more often as well as analytical- and decision-making capability
From Houthi attacks to Russian activities, both the Asia-Pacific and Europe have become flashpoints for suspected assaults on undersea infrastructure.
