Thanks to TooHuman on IRC, I figured out the source of the 
problem.

forum.dlang.org is CNAME-aliased to 
forum.kimsufi.thecybershadow.net, which before pointed directly 
to the correct server IP. Yesterday I moved my personal website 
(thecybershadow.net) from an older server to the same server as 
the forum, so I updated its IP, and changed 
forum.kimsufi.thecybershadow.net to be a CNAME-alias of 
thecybershadow.net. However, for some reason, this caused some 
DNS resolvers to follow the redirect of 
forum.kimsufi.thecybershadow.net but use thecybershadow.net's old 
IP, which caused requests to go to the old server. For HTTP 
requests, this continued to work fine, because the old server is 
configured to act as a reverse HTTP proxy for domains moved to 
the new server, however that isn't done with HTTPS, which is why 
for some users the forum fails to load via HTTPS.

As far as I can tell, this is a temporary problem, and should 
clear up once DNS caches expire.
