I am trying to remember looking at the times of the posts on 9/11/01, it seems after 10:30 AM or thereabouts there was very little posted, I can’t remember were the FR servers down for most of that day from overload, I remember it was difficult to get to a lot of sites on that day.
As I recall, FR was up all day. I was checking in, as it was (and remains) the best place to sort through breaking news accounts, and don’t recall any major disruptions. Admittedly, the day was something of a blur, calling my parents and sister-in-law to see if they’d heard anything about my brother.
