I'm not sure I understand how that tweet offers proof the banks went offline. Only one of the four charts in that tweet shows a number of reports that I would consider significant (3000 vs less than a hundred for the other three).
Writing "@dang" does not notify dang, though he sometimes stumbles across these questions. Email hn@ycombinator.com. I have always received a response to my emails in a day or less.
If I understand correctly, "flag" mostly doesn't come from dang. It comes from other users.
I think dang can flag a post himself, but more likely it's from users. It takes more than one user to mark it as flagged; I don't know how many it takes.
Sure, but 1 thing going down doesn't take down your entire corp. That would be some extremely bad design.
Doesn't really explain all the major banks going offline at around the same time. https://twitter.com/AB_inmate/status/1494079461347643392
No conspiracy. This is just people reacting to the news they will be seizing the accounts of political opponents.
