I'm getting a 404 as well from London. After trying multiple times with
curl I did get one 200 response, but it's mostly 404s.

It looks like some of the mirrors have it, but not all:

$ for h in $(dig +short -tA www.mirrors.postgresql.org); do echo -n "$h: "; curl -i -k -s -HHost:www.postgresql.org "https://$h/docs/release/14.2/" | grep ^HTTP; done
 72.32.157.230: HTTP/2 200
 87.238.57.232: HTTP/2 404
 217.196.149.50: HTTP/2 200

$ for h in $(dig +short -tAAAA www.mirrors.postgresql.org); do echo -n "$h: "; curl -i -k -s -HHost:www.postgresql.org "https://[$h]/docs/release/14.2/" | grep ^HTTP; done
 2001:4800:3e1:1::230: HTTP/2 200
 2a02:c0:301:0:ffff::32: HTTP/2 404
 2a02:16a8:dc51::50: HTTP/2 200

Despite the name, they're not actually mirrors. They're varnish caches. By the looks of it one of them cached a 404 (probably someone tried to access the new page before it really did exist). I've purged /docs/release now, and everything is returning 200.
