Overview
- Estonia reported five submarine cable outages affecting links to Sweden and Finland and a domestic connection to Hiiumaa, citing operator data from recent days.
- Faults were logged on the CITIC Estonia–Sweden cable from December 28, on Telia’s Läänemaa–Hiiumaa link, and on Arelion’s Hiiumaa–Sweden route in two places from December 30.
- Two cross‑border connections between Estonia and Finland failed this morning, including an Arelion link and Elisa’s Tallinn–Helsinki cable.
- Estonia’s ministry said the first three disruptions were likely caused by recent storms, while the two Estonia–Finland breaks remain under investigation.
- The Finnish Border Guard located a suspected vessel in Finland’s exclusive economic zone, recovered an anchor chain linked to the Elisa cable damage, and police have opened a criminal case, with Estonian prosecutors coordinating on next steps.
