[tor-relays] how to distribute pgp public key?

If I want to include a reference to my public PGP key on Atlas using the ContactInfo field on my relays, what's the best way to do it? Should I upload my key to some of the public keyservers and then list the fingerprint on Atlas? If so which keyservers are recommended?

I had a thought to publish it on my relay's DirPort (using DirPortFrontPage and a simple html doc containing the public key). Then I could just provide a link to the DirPort in ContactInfo.

Is there a better way to do this?
