#Underwater #cables are a vital piece of the #AI buildout and #internet — investment is booming
Over 95% of international data and voice call traffic travels through nearly a million miles of underwater communication cables.
Investment into new #subseacable projects is expected to reach around $13 billion between 2025-2027, almost twice the amount that was invested between 2022 and 2024, according to telecommunications data provider firm TeleGeography.

Update on the Estlink-2 #subseacable cut last December:

"Finnish authorities [...] have charged the captain and two senior officers of a Russia-linked vessel that damaged undersea cables last year between Finland and Estonia."

Finland charges top officers of Russia-linked vessel that damaged undersea cables

Finnish authorities say they have charged the captain and two senior officers of a Russia-linked vessel that damaged undersea cables last year between Finland and Estonia. Monday's statement says they denied the allegations of aggravated criminal mischief and aggravated interference with communications. Authorities have said the vessel dragged its anchor to damage the Estlink-2 power cable and communication links between Finland and Estonia on Dec. 25. The Kremlin previously denied involvement in damaging the infrastructure. For the West, such incidents are believed to be part of widespread sabotage attacks in Europe allegedly linked to Moscow following its full-scale invasion of Ukraine in 2022.

Towards a Non-Binary View of IPv6 Adoption

Twelve years have passed since World IPv6 Launch Day, but what is the current state of IPv6 deployment? Prior work has examined IPv6 status as a binary: can you use IPv6, or not? As deployment increases we must consider a more nuanced, non-binary perspective on IPv6: how much and often can a user or a service use IPv6? We consider this question as a client, server, and cloud provider. Considering the client's perspective, we observe user traffic. We see that the fraction of IPv6 traffic a user sends varies greatly, both across users and day-by-day, with a standard deviation of over 15%. We show this variation occurs for two main reasons. First, IPv6 traffic is primarily human-generated, thus showing diurnal patterns. Second, some services are IPv6-forward and others IPv6-laggards, so as users do different things their fraction of IPv6 varies. We look at server-side IPv6 adoption in two ways. First, we expand analysis of web services to examine how many are only partially IPv6 enabled due to their reliance on IPv4-only resources. Our findings reveal that only 12.5% of top 100k websites qualify as fully IPv6-ready. Finally, we examine cloud support for IPv6. Although all clouds and CDNs support IPv6, we find that tenant deployment rates vary significantly across providers. We find that ease of enabling IPv6 in the cloud is correlated with tenant IPv6 adoption rates, and recommend best practices for cloud providers to improve IPv6 adoption. Our results suggest IPv6 deployment is growing, but many services lag, presenting a potential for improvement.

Bojāts LVRTC optisko šķiedru kabelis Baltijas jūrā; NBS apseko, iespējams, iesaistīto kuģi

Svētdienas agrā rītā ir bojāts VAS "Latvijas Valsts radio un televīzijas centrs" Baltijas jūrā esošais zemūdens optisko šķiedru kabelis, informēja centrs. Šī centra datu pārraides uzraudzības sistēmā tika fiksēti datu pārraides pakalpojumu traucējumi posmā Ventspils - Gotlande. Šobrīd ir pamats uzskatīt, ka kabelis ir būtiski bojāts un ka bojājums ir ārējas iedarbības.
