This was reported to be caused by severed cables in two different places. And I read some speculation/claims that this cut the primary and the backup systems simultaneously, which would explain why this lead to a complete outage in a system that should have quite some redundancy.
Of course we don't really have enough reliable information right now, but it looks a bit like this would require quite a bit of detailed internal knowledge to know which two cables you need to cut to shut this down entirely. Which would suggest more sophisticated actors might be responsible for this.
- tastroder 4y agoWhile the GSM-R system belongs to the rail system which is dubbed critical infrastructure much of it is either publicly documented and/or shared between a rather large number of operators. So far I didn't read anything that would indicate that this disruption required more than somewhat specialized domain knowledge and a bit of experience in the industry.
- bombcar 4y agoIf they were cut simultaneously or close enough AND they weren’t routed together (I’ve seen cases where the main fiber and backup fiber were in the same trench for a distance, backhoe magnet) then it’s pretty good guess it’s intentional sabotage. However if one line had been cut at some point earlier and they were ON the backup line when that got cut, it could be sabots or it could just be generic construction mistakes/idiocy.
- LaputanMachine 4y agoApparently two lines were sabotaged earlier today, one in Berlin and one in Dortmund [1]. The two cities are around 500km / 300mi apart.
