Best I can do right now is the Nanog mail list that day/week... https://archive.nanog.org/mailinglist/mailarchives/old_archi...
It was an odd time since we were technically in peace time and suddenly thrown into this situation. A year later (Mar. '03) we were watching jets fly over Iraq on tv while we preparing for a funeral detail for one of our Blackhawk pilots.
Still hard to believe it's now so long ago.
I lived in Norfolk VA and IIRC we had 3-5 carriers moored. They all dispersed away from the shipyard when it happened. 20-25k Navy just vanished from town.
My roommates and I spend the next week completely glued to the television. Which is why this interface is particularly great for capturing that feeling, but it is tough to rewatch.
The at 8:46 you see the first sign of something wrong, a smattering of errors about how the Cantor Fitzgerald API was down, and the butterfly effect the outage had on other systems. The computers were chatting about how something was wrong ahead of any people.

Reading IRC logs from back then is also really interesting. And Nanog had a really interesting slideshow/powerpoint deep dive on the infrastructure outages that occurred. And of course the SomethingAwful thread that's been posted before. https://news.ycombinator.com/item?id=7990991
RE: this specific site.. interesting UX/UI choice. I was hoping I could click the times in Timeline of Events and be sent straight there but it seems like I have to put times specifically in the Controls section. Anyway, this is neat.
