I actually hope they do rush - not with conclusions but with diagnostics - just a little.

If it's another spontaneous breakdown (there have been some) then there's plenty of time. If however someone damaged it, then hours = kilometers.

However, this cable has previously had transformer malfunctions, a short circuit at the site of climbing onto ground (ground shifted over years - I hope it hasn't shifted again), but in light of recent power games on the Baltic sea, it would also be a candidate for plowing with anchors.

Timing is pretty annoying. Baltic countries are leaving the old Soviet power grid synchronization area (physically disconnecting from Russia and Belarus and synchronizing with continental Europe) really very soon (in about a month) and nobody here would appreciate power connections being disrupted at this time.
