    We do not know if this is made with malice by Microsoft, if it is some sort of mistake, or if some of their cloud customer is running the attack.
  

  It surely doesn't take much thought to realise that the first option is obviously ridiculous. It's almost certainly the third, and possibly the second.

  MS publishes Azure IP ranges[1] so it should be trivial to check if the attack originates from those or something else.

  MS also has abuse contact exactly for this purpose[2]. I have no experience what their response is there, but probably worth a shot anyways.

  The front page of https://gmplib.org/ has two other undated updates that the current server is too slow because of meltdown and they're going to replace with it with an epyc server in mid April.
