To answer the thread title, Josh at easywdw recently posted on FEA downtime. During my recent trip, I ran into closures on 2 different days before I finally got to ride on my last day. According to Josh's chart, one day I just hit it at the wrong time and should have been patient, but the other day, when I went back by a couple of times, turns out it was down most of the day.
Short answer to the thread title, apparently yes.
