I have been using pgp for years now, but usually email the person my public key and compare its fingerprint over the phone or give it to them in person on a stick. I thought I might try out the key servers a while ago and uploaded a public key with:
gpg --send-keys --keyserver keyserver.ubuntu.com C3582062D32255323DEABDEEFAA3632602ACD45
...which worked in that the key made its way onto that keyserver, and on the web page of http://keyserver.ubuntu.com/ if I search for a substring of the email address associated with that ID, it finds it. (keyID above is not the real one)
According to this answer, the main keyservers are :
..but I definitely could not find my key anywhere on the other two main servers even months after the upload push from the terminal.
Does anyone know if these keys are really supposed to propogate by themselves between the servers within a few hours or not? If so, what have I done wrong?
Otherwise, what is a list of all the keyservers where the key should be deposited such that all mail programs can retrieve them? Is it just those three?
