Ah, I disagree here. For instance, {demo,flask,www}.sagenb.org are
all once again misbehaving (really slow) as I type, whereas the one
for this summer's PREP (hosted not at UW) is working fine and quickly.
Now, how do I disagree? Not in that there is something wrong with the
code in demo! demo.sagenb.org being slow is a SYMPTOM of whatever
problem in the other ones is causing the trouble. After all,
sagenb.org was on flask (not the latest, though) just a week ago when
we had 300+ successful open worksheets at a time, right?
I have no idea, but a futile guess is that www.sagenb.org being on the
new codebase is causing the actual machine to grind to a halt (they
are all on the same server, correct?). I'm otherwise not having any
connectivity issues - only on the sagenb.org farm. Even sagemath.org
works fine.
