It's been down for a day, and may be down for a few more. Looks like "Just build your own Internet" isn't a viable option for internet communists, everyone must learn of their peaceful ways by force.
Trying to get to Saidit redirects you to Saidit's Subreddit, in a sad state of affairs.
EDIT:It's come back up since then. Updates in the link.
By catering to some... unsavory elements of the left they were kinda asking for it. But I still don't consider it the same as deserving it.
If a kid is told not to touch a hot stove element because it will hurt them, and this is repeated several times, and the kid touches the stove and burns their hand... The punishment for disobedience is extreme pain that they didn't "deserve", it's a minor infraction to touch something you're told not to, that causes no damage to that thing, Justice-wise the kid did not "deserve" to be burned...
But you still stand there and say "I told you so, you git."
