Colocation · Transit · Dark fibre · Routing silicon

The layer under everything.

Starlight Servers builds and operates physical network infrastructure: buildings, power, fibre, and the forwarding silicon that decides where a packet goes next. We have done it since 1979.

We sell no software and no services on top of other people's hardware, and we have never operated a consumer product. When something on the net stops working the fault is usually in a building, and twelve of those buildings are ours.

A data hall photographed down the centre of a cold aisle: two facing rows of black cabinets running to a vanishing point, their perforated doors showing ranks of blue and amber indicator lights, pale floor tiles with grated vents down the middle, and ladder trays overhead carrying bundles of blue and white fibre. — **DNM1 · Dunmore Deep · Hall 2.** Cold aisle, looking north. Commissioned 2022, 800G fabric, five halls, 70 MW contracted. Overhead trays carry fibre only; power is under the floor, on the other side of the slab, and the two are never in the same tray. Containment doors are shut in normal operation and are open here because the photograph was taken during a cable audit. 2026-04-11.

What we operate

01 · Colocation

Space, power, cooling, and the contract that says so

Cabinets to caged halls, 4 kW to 42 kW a rack, in carrier-neutral buildings we own freehold. Two independent feeds, N+1 mechanical as standard, 2N where the hall is sold that way.

Availability 99.999%, measured at the busway.

02 · IP transit

AS64502, and 41,880 route-km of our own fibre

Full tables, no default, BGP communities documented in public. We do not oversubscribe the backbone and we publish the utilisation curve that proves it.

Commits from 1 Gbit/s. Priced in credits, per Mbit/s, per month.

03 · Routing & peering

Open at fourteen exchanges

380 peers, open policy, no ratio requirement, no port fee for settlement-free interconnect at a common exchange. Private interconnect inside our halls is a cross-connect and is priced as one.

Peering requests answered in two working days.

04 · Routing silicon

Seven generations, designed here

We have built our own forwarding silicon since 1988, when the merchant parts could not hold our routing table. SL-7 is in the halls now and SL-8 is in RTL.

Not sold, licensed or sampled to anyone.

Enquiries

Colocation and transit quotations are issued against a signed NDA and a floor plan. We do not publish a configurator because the answer depends on the building.
