This afternoon I was able to upload 1 of 3 and download 2 new wu. It took several trys to do this. I am sure the server is slowly catching up. Great work SETI.
Since I have  work I turned off network connection until work needs to upload. This way if all did this it wouldn't tax the server with repeated request.
BOINC should put a set time interval in the next version like 1,5,10 30 minutes 1,2 hours only. This way Boinc won't contantly connect for request in the shortest intervals.
I had 3 wu to upload and 2 downloads and all stopped and started  many times with a minute or two intervals before it increased to 15 minutes then an hour. I figure this to be wasted connections.
Do the SETI programmers have an email I send this info to .I don't think they read these forums. Or maybe I'm wrong.
