I have bounced the web server several times today. Something is gobbling up more CPU time than it should, and I'm trying to debug what it is, so I can fix it.
So if you get a "Connection refused" error, or something like that, be patient. I won't let the server be down for more than a minute or two at a time.
I may also "shut off" parts of the sites at different times, in order to track down the culprit. Again, I'll only do this for a minute or two, so if you see something weird, just try again in a minute.
