idpy.org is hosted as a github-pages website (Jekyll SSG). GitHub
Pages now support HTTPS for sites with custom domains through
LetsEncrypt.
Currently,
idpy.org is using A records to point to github. The A
record IPs have now changed and should be updated, in order to support
https.
Alternatively, we can set an ALIAS or ANAME record for
idpy.org and be
safe from future (IP) changes.
If the DNS admins can look into that, it would be great ;)
