Thanks!
I didn't have the CentOS repos enabled.. don't know why, I dont think I've changed it!

You will most likely receive a set of updates then tonight.
The repos not being enabled is most likely due to your server being installed using a previous release and being upgraded from there to 7.3. In the past only smeos, smeupdates and smeaddons were enabled, somewhere around 7.x (don't know the exact version) a design change was made and the base and updates repository of CentOS were implemented lowering maintenance for the core devs.
The devs decided to enable base and updates on new installs, but leave it as is (only smeos, smeupdates and smeaddons enabled) so sysadmins could decide for themselves.
