Confusing key servers

I have an understanding that the key servers internally sync all the details, but this is not happening with MIT key server. My 'gpg.conf' file updates the 'subkeys.pgp.net' server.

'keyserver hkp://subkeys.pgp.net' in 'gpg.conf' confirms the same, but when I verify my signatures on the web, it is intact with http://subkeys.pgp.net:11371/, but the same signatures are not reflected in http://pgp.mit.edu:11371/. Not sure what I am failing to understand. I have done some basic RTFM with gpg command too.
