I cannot access the docs at the url advertised in the README and elsewhere.

The internet. No special VPN or anything, accessing from the UK.
Go here: https://create-react-app.dev/
I can read the documentation.
I cannot.

It's up for me and as it looks like for everyone else too.

Ah I just did some more digging. I could not curl it in the terminal, but I could access it via mobile on the same network.
Turns out https://superuser.com/questions/1374892/dev-domains-dont-resolve fixed for me.
Somehow somewhere I had this file /etc/resolver/dev created which looked like this:
# Lovingly generated by Pow
nameserver 127.0.0.1
port 20560
If you delete that file it works.
sudo rm /etc/resolver/dev
Closing as fixed
