I personally believe this was a state actor who did it. If it was a SCADA system attack to overpressure the pipe, a state actor is the most likely culprit as SCADA knowledge isn't that common among laypeople. Personally, I think powerful explosives were used, at which point it'd definitely be a state actor because who else would have access to high power explosives, and then place them hundreds of feet below sea level next to a pipeline?
