Supplier of the Smartbunker connectivity backbone


Failsafe technology from BT.

Zero hassle. Zero risk. 100% guaranteed uptime.


Smartbunker’s latest optical network technology from BT allows data to be transferred via two totally independent SDH fibre optic rings. Each ring supplies two separate fibre optic cables (each containing 96 fibres), any one of which is capable of supporting the full load of the data centre.

The cables are then routed via 3 entirely separate pathways from the building to connect with BT’s nationwide ‘Colossus’ Core infrastructure – which now underpins all of BT’s IP services – with no points of convergence outside of the facility.

In other words, Smartbunker is protected by triple-failsafe network connectivity. Add to this our location - deep underground in a remote ex-NATO nuclear bunker - and you'll understand why we're able to guarantee 100% uptime - and mean it.

Why BT?

BT supports more traffic, more reliably and more flexibly than any other UK IP services provider. In research and development, future technology, evolution and design, and in the capacity for effective ‘future proofing’, BT is without equal.

So it's no accident that we've selected BT as technology partners to provide failsafe connectivity for our customers – 24x7x365.

Zero hassle. Zero risk. Zero downtime – guaranteed.
