The biggest question is whether or not their systems were able to execute margin calls. If they were down this long, that to me suggests data got corrupt and they've been restoring from backups, etc, which means maybe all their services were inactive. If that's the case then could the margin system be active, or are people (and potentially RH) sitting on oversized losses if they were short today? What happens tomorrow if their margins kick in and sell at the open, and then the market drops? Lots of very interesting questions that need to be answered.
