Someone has been trying to force their way into this blog’s web server. Today I discovered that a very large proportion of server CPU (up to 80%) was being used to run a process intended only for use by the web host. That’s probably the reason the blog has been going down from time to time. With help from a Google search I’ve closed that door.
I hope that means the downtime that’s been plaguing this blog is over. I’ll keep an eye on the processes to make that’s true.
In the meantime I’ve re-enabled some capabilities here, including user editing of comments.
