Can anyone explain why there wasn't any BGP activity on the Finland-Germany systems when the cable broke, while for Lithuania there was a massive spike?
Unfortunately it's been a long time since I learned about BGP, if anyone could help out here I'd be grateful.
One important question that I'm unclear on is how long it takes to fix one of these cables. If it takes months then that is quite a wide window in which an attacker could incrementally take down cables.
