Total chaos at immigration / customs. No signage whatsoever. Lines should be separated by nationality + passport type, but aren't. Instead they shuffle everyone into the same queue and then try to rearrange as they go along, which works as well as you might expect. Global Entry machines all offline. Half the electronic passport scanners are dead as well. I used one of the working ones, but instead of continuing out the exit, was routed back through the entry into another line, which later fed back through the passport scanners a second time, and then was routed to yet another line. No apparent order to anything. Great first impression...

[Edit on next trip: used Mobile Passport app to speed up immigration and customs. Had the opposite effect. Line was slower than the normal queue. Customs said the app wasn't working so everyone was routed to secondary inspection. Absolutely abysmal system]
