It wasn't mentioned there, but for point of comparison, look at FDIC turnover time. If a bank shuts down and goes into FDIC receivership, it re-opens the next day. In some complicated cases, they shutter on Friday and re-open on Monday while working over the weekend to get things in order.
Yes, that's a completely separate ball game, and is less complicated by the fact that they prioritize re-opening the brick and mortar banks themselves not a purely online bank. But - it feels like it should be handled better in a software world, not worse.
Oh well :\
