Recent issues with OpenPGP key servers are likely to prompt PGP users to advertise their keys via alternative methods.
There is currently a DRAFT RFC (draft-koch-openpgp-webkey-service) for publishing keys where an infrastructure such as DANE is not yet in place.
For example, the key for [email protected]
would be located at
https://openpgpkey.example.org/.well-known/openpgpkey/example.org/hu/apr3aj3jqcf89yd69qd8pkjp3pzawxhx?l=example
