Last night I found both of my forums down. At first I thought that they had been hacked. I contacted my host's on-line tech support via chat, and they told me there was a problem with my forum software. So, searched the archives of the forum software tech support forum, and found that other forum administrators have had the same problem with the same host. Just in case it was another problem, I reported the outage to the forum software tech support forum. This morning I found both forums running again.
My apologies to anyone who found the forum down. It appears that I will have to find another hosting service to move the forum to, which is likely to result in extensive outages while the transfer of resources takes place. Hopefully it will not take a month next time, as I have learned a lot in the process of moving it last time.
