This website tracks the reddits that went dark. Right now 4735 subreddits are dark while 8829 subreddits went dark at any time.
This market will resolve to YES if by the end of Monday (GMT-03, São Paulo time), 75% of the subreddits are back. This means that the smaller number divided by the bigger must be smaller than 25%.
I won't bet on this market.

@MP Since you haven't created a followup market, I hope you don't mind that I've created one here using your same source for resolution?
I've got invested in this question now, so I wanted to keep it going with a deadline which looks pretty realistic (it should be pretty close to 25% at the close of this market if subreddits keep opening at the same rate as the past few days)
