Changed my DNS servers (on my router) to
208.67.222.222 and 208.67.220.220 and it now works.

I have long suspected that DNS censorship will be a thing going forward. It shouldn’t be a practical way of censorship with who knows these days. Keep an eye on this.
These are the DNS servers from OpenDNS.
