How do you know? Someone else posited the theory that the frontpage service has to search for posts for too long due to the blackout. How do you prove this is not the case?
Another sibling comment was added 2 minutes ago, where Reddit themselves state that the blackout is the cause:
> According to Reddit, the blackout is responsible for the problems. “A significant number of subreddits shifting to private caused some expected stability issues, and we’ve been working on resolving the anticipated issue,” spokesperson Tim Rathschmidt tells The Verge.
Maybe you should think a bit harder about the difference between "this thing that is actively happening could be the cause" and "aliens could be the cause"?

EDIT: Reddit themselves confirmed that the outage was related to subs going private.
