I read somewhere on one of these federated sites (I'd have to dig through my history to find it) that it's essentially the spaghetti code that is Reddit. This person, who claimed to have worked at Reddit years ago, said that the aggregation engine for things like r/all is very inefficient and when thousands of subreddits went dark it wouldn't be able to parse (or something like that).
