It's pretty darn clear we got ops going on in the Vatican and Pakistan. The blackouts are cover. It's also pretty clear @Jack has some serious karma coming to himself and his little business from POTUS. I think it likely that Twitter will be raided but not until the net is largely taken down to prevent a huge barrage of pre-canned tweets from whining about gestapo tactics.
So I think it's likely the net will be taken down in a few days and for a few days to cover some serious ops. That's when and why the EMS will be brought into service. When the net comes back up, twit and goog and fb and the rest their kind will have been cleansed of their censorship and free speech will be back.
The Internet is an internetwork of networks. Thus, the name “Internet”. Yes, I capitalize it as it is THE worldwide internetwork. It is a collection of interconnected networks. Why is this important? You don’t have to take down the whole Internet in order to take down twit/goog/fb. All you have to do is adjust internet routing at key locations to send all traffic bound for the public address ranges of those entities to null interfaces thus dropping that traffic into the proverbial bit bucket. There are key points along the Internet backbone where this would have to be done. Easy peasy.
