I’ve spent the last few hours fighting the server software to try to get the site back up and running. It went down overnight and no amount of rebooting would bring it back to life again. I’ve ditched the old web server and installed something else, and finally imposed my will on it strongly enough that the site is back up again.
Until I can make sure the new setting are okay there may still be some instability. Hopefully normal service, i.e. almost complete silence, will resume soon. I am going to do a quick links post though to more thoroughly test out posting later, as it’s well overdue.
