After revoking a key and sending the revocation to MIT's keyserver, I noticed that the key is listed as such:
pub 2048R/XXXXXXXX 2011-01-01 *** KEY REVOKED *** [not verified]
Who is responsible for the 'verification of the revocation'? Does the owner of the key do this verification? If so, how is this accomplished? Do other people sign the revocation and at a certain point it becomes verified?
