I’ve been having problems with an install all night, I had just assumed it was my really crappy ISP’s fault
Most things are working again for me, certainly the auto DNS which is what I was tearing my hair out over is fine.
You mention image downloads… I’ve tried several, most commonly the ARM and 64bit PC ones. I’ve never managed to boot from them.
The other thing that was down and doesn’t seem to have resolved is the Google domain API link and for me, the diagnosis was working most of the time, but only in Chrome
