*** one.one.one.one can't find kitz.co.uk: Server failed

This is with a router reboot and Workflow turned off. (Workflow is TTBs virus detection) looks like it is Cloudflare on TTB for some reason. If it were the router why would all other sites work?

No idea what the #53 means, but seems likely...

Changed to TTB DNS Servers and all working. There is a thread on Kitz with people getting intermittent connectivity to the site so have put my 2p in about 1.1.1.1. Thanks for the confirmation Bill.

Thanks, I wondered if it was... but there's a lot of things in this life I'm unfamiliar with and terminal commands under MacOS is well up there

Of course with these IP addresses such as 1.1.1.1 and 8.8.8.8 you will be connected to a local copy, which may be a UK or Europe data centre with a lot of servers that can respond. Quite easily one of those servers has had a problem, and eventually it has been detected, and removed from responding, so others take up the response.

"hyper scale" they like to call this, systems of the scale of sites like Facebook, which are available everywhere in the world at the same time. Very different IT engineering to that which most IT professionals get involved with.
