Update – 01-11-2018
Well, it was good while it lasted. The gremlins hit this afternoon, so the site is now back under the protection of Cloudflare!
In an attempt to resolve the current problems with caching I have changed the site so that it no longer uses Cloudflare. It takes up to 24 hours for this change to propagate through the internet.
