I did notice something strange a few days ago. If you ran a search on Twitter, and scrolled down, it would mysteriously stop showing tweets past a certain time (July 1st, in my case). I wasn't sure if this was an internal change, or a bug of some sort. Maybe this is unrelated to the outage but strange coincidence.
