So, funny thing. Both pipelines (nordstream 1&2) that deliver gas directly from Russia to Germany have developed leaks within hours of each other. The other actually developed two separate leaks, so the total number of leaks is three.

The odds of this being random are basically zero, and the explanation seems to lean heavily towards sabotage.
It's not clear who would benefit from this and how, especially since both pipes are currently closed (although they do still have some gas in them). While Russia is naturally the first suspect, there's no obvious reason for them to do this. After all, they do want to get back to selling that gas eventually.
Since these are underwater pipes running at the bottom of the Baltic Sea,
sabotaging them is far from a trivial operation, which limits the realistic options.
There are of course plenty of parties that would like to put a total stop to the gas trade between Russia and Germany, from Russian and German hawks to aggressively anti-Russian countries like Poland, but considering how damaging it would be to a country's reputation if they got caught (the leaks are a non-trivial safety hazard currently), it's kind of hard to imagine who would take such a risk.
Swedish national seismological center reports that it registered two explosions at about the right time and place for them to be possible explanations for the leaks.
Interesting sideshow in any case.
