I notice the FFF forum servers are still intermittent today and the past few days. There are periods where the speed slows way down and at times gives the "too many connections" error message, and other times when the performance is fast. Of course, ideally the servers could be worked on so they are reliably good performance all of the time.
I would take the periods of slowdown/errors as warning sign. I'm getting several periods of extreme slowdown and "too many connections" errors on my FFF IPB s3 forum this afternoon, currently 1:30PM PacificTime. Speeds back up periodically.
