Russia partially disconnected households from the global internet to test its "sovereign Internet" system in the early hours of July 5, Russian media outlets have reported.
From what I've read, the troll farms mostly operate funded by Russia but are physically located outside of Russia. For example, Macedonia had quite a few.
I think it should be a bit worrying for people outside russia too. This is literal practice for a world war scenario. We can meme all you want but I don't like seeing countries crossing items in that checklist.
