I've been bumping into this a bunch trying to research different neighborhoods of Washington, D.C., for an upcoming three-month stay. A lot of useful info is locked up in r/washingtondc right now, with much of it missing from Google's cache and the Wayback Machine. I still support the blackouts—I used to mod a default subreddit—but I wasn't expecting this particular effect!

(Tangentially, anyone know how the Mount Vernon Triangle area is these days?)
