HUBS: Gigabit copper between oxygen and the HUBS router in our rack.

Summerhall: Gigabit fibre between switch-g11-d and the Summerhall server room. This was originally intended to be connected directly to oxygen, but the SFP was incorrectly configured so we are currently using a VLAN via our switch.
