Was able to apply a DSU ~2pm EST. DSU got in but never received the updated receipt with the price knocked down to the original price.
I had another reservation that I applied a DSU to right before the system went down and had never received updated receipt. Took about 30 minutes and they were able to update that one.
Looks like I'll likely just need to wait on the new one for a couple of days before getting it re-priced appropriately.
