Sadly, my server has succumbed to the heat here in Portugal. Perhaps hiding it under the bed in the spare room was not such a good idea. Anyway, one of the disk drives has failed and the mirror copy is also suspect so I spent a long time making yet another copy of the critical (irreplaceable) data to a spare disk.
As a temporary measure I have setup my Raspberry Pi as a web-server, and transferred the web site to that.
It's a bit slow and probably won't handle lots of connections but Google will keep on scanning it !! With only a 32GB storage I will not be making many updates but most of the site seems to work for now.
Next task - try to get the webcams up and running ...
