Yesterday afternoon slow down

Starting about 12:30 PM Thursday, uploading response times got really slow, and stopped responding around 1:30. It picked up for a while and then was really slow until about 2:30. Tuesday thew were 3 periods of slow or dropped uploads. There was a slowdown on Wednesday, at 4PM for a half hour or so. Today has been fine. The status page doesn’t mention any issues, nor are we informed of updates, upgrades or repairs. Is this kind of instability going to be the standard from now on?
