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.

Record Keeping


As of 21/02/2022 for 1 year, Tardis Project are borrowing They used to have colo in UoE but were recently kicked out and have no IP space. FDX is giving them paid colo in the FDX office but no IP space as of yet. As a gesture of goodwill Hacklab is letting them borrow this space to get them on their feet.

It is currently static routed to an FDX router in the rack and then handled by FDX to reach Tardis.

For any questions on the agreement please contact Cameron Sharp
