School boy error

For about a week I have been, on and off, fighting my browser and Ubuntu Desktop to flush its DNS cache after struggling to reach one of my websites.

After a few minutes of swearing I'd set the problem aside and revisit another day.  The domain name was resolving to my old host. It was fine for other people, and worked for me if I dual-booted into Windows 11 (🙈) on my desktop. 

Tonight, a light-bulb moment 💡🤯

For some reason I had manually entered the old IP address in my hosts file.  I don't recall doing it, but it was no one else!

Can I blame the dog?
