Rack space specification

UK data centre rack space, specified in full.

Every figure for a full rack in our own UK facility: the feeds, the cooling targets, the cabinet, the uplink, the IP allocations and what remote hands covers. No brochure adjectives.

The facility

Three things that decide whether colocation works

Rack space is a commodity right up until something fails. What separates one facility from another is what happens on the second power path, how quickly somebody can physically reach your cabinet, and whether the bill matches the quote.

  • Two power paths, not one plus hope

    Dual A+B feeds on separate PDUs, behind UPS and generator. Maintenance on one path is a scheduled note, not an outage, and cooling is N+1 so a unit can be taken out under load.

  • Network built for throughput

    10Gbps as standard on enterprise switching, dual-port with LACP if you want it, and a transit blend across multiple Tier 1 upstreams with redundant routing paths.

  • Pricing with the costs already in it

    Power allocation, bandwidth and IP resources are in the monthly figure. Remote hands has an included allowance and a published hourly rate, so there is no surprise cross-connect invoice.

  • Access on your terms

    24/7 biometric entry with every entry logged, CCTV across the facility with 90-day retention, and door sensors on your own cabinet that alert on unauthorised access.

  • Numbers you can check

    Power metering with monthly consumption reports, environmental monitoring on temperature, humidity and water, and proactive alerts the moment a threshold trips.

  • Hands that are already there

    We own the building, so remote hands is our own team walking to your cabinet rather than a request routed through a landlord's ticket queue.

A+B power

What the second feed is actually for

Two independent paths arrive at the cabinet and land on two PDUs. Dual-PSU equipment takes one from each. That is the whole trick: a fault or a planned change on the A path leaves your equipment running on B, and nobody has to be woken up.

Add-ons

Optional extras, priced transparently

None of these are needed to get started. All of them are quoted before they are added, and they appear on the invoice as themselves rather than as a line called "services".

  • Additional PDUs
  • KVM over IP
  • Cross-connects
  • Private cages
  • Out-of-band management
  • Dedicated wavelengths
  • Additional VLANs
  • Backup connectivity
EdgeProt

Filtering included with every full rack

Not an upsell and not a manual activation. Traffic arrives through EdgeProt from day one, which is built for hosting workloads rather than for generic scrubbing, so it holds bandwidth and latency while it is filtering.

  • 6+Tbps Network-wide mitigation capacity
  • <2ms Added latency, including during an attack
  • L3 to L7 Volumetric, amplification and application-layer
  • 24/7 Always on, with no manual activation

How it works

  • Built for hosting and game workloads
  • Flow analytics learn your normal traffic
  • Anomalies fingerprinted and dropped in seconds
  • Absorbed near the source on an anycast network

What it covers

  • Volumetric floods
  • Amplification and reflection
  • Application-layer abuse
  • Multi-vector attacks

What you see

  • Live packet rates and attack types
  • What was blocked, and why
  • Real-time mitigation responses
  • In-depth attack reporting

If you need more

  • Premium tiers for advanced Layer 7
  • Custom rulesets
  • Behavioural tuning to cut false positives
  • Quoted before anything is enabled

The full detail, including per-tier capacities, lives on our DDoS protection page.

The network

Where your rack sits on our network

The uplink from your cabinet joins the same network as the rest of the platform: UK core into London for transit and peering, with edge capacity beyond it.

  • Core sites
  • Edge locations
  • Fibre runs

The building

We own the facility, not a contract in it

Most colocation is subletting. Our cabinets are in a building we own and operate as NorwichDC, which is why remote hands is our own engineer walking down a corridor.

From £250per month, monthly rolling

Feed sizes, uplink options and the full price list are on the full rack colocation page.

  • Your own key, 24/7

    Biometric entry to the building with logged access, individual keys for the front and rear cabinet doors, and door sensors that alert.

  • Monitored continuously

    CCTV across the facility with 90-day retention, plus temperature, humidity and water detection with proactive alerting.

  • Engineers on site

    24/7 on-call, UK-based, with direct escalation. 30 minutes of remote hands a month included and £60 per hour beyond it.

Rack space questions

A private, lockable 42U cabinet with 40U usable, dual A+B power feeds, dual smart PDUs, a 10Gbps uplink, a /29 of IPv4 and a /64 of IPv6, cabinet door sensors and 30 minutes of remote hands a month. Pricing starts at £250 per month and is set out on the full rack colocation page.

Feeds are available at 16A each, 32A each, or dual 32A. Power is metered and reported monthly, so you can see your actual draw rather than guess at it, and move up a feed size before you are running close to the limit.

Two independent feeds arrive at the cabinet, each on its own PDU. Dual-PSU equipment takes one from each, so maintenance on one path, or a fault on it, does not take your equipment down. Single-PSU equipment can be split across the two PDUs so a whole rack never depends on one feed.

Yes. We support BGP sessions so you can announce your own ASN and prefixes, and bring your own IP addressing with you. Reverse DNS for the addresses we provide is yours to manage in the portal.

30 minutes a month at no charge, covering the things people actually ask for: a reboot, moving a cable, swapping media, or a photograph of what is on a screen. Beyond that it is £60 per hour, quoted before we start.

Yes, 24/7, through biometric access control with every entry logged. CCTV covers the facility with 90-day retention, and your cabinet has door sensors that alert on unauthorised access.

Our commitments and the service credits attached to them are published in our service level agreement. Credits are applied automatically when we miss them; there is no claim form.

No. EdgeProt filtering is included with every full rack from day one, covering Layer 3 through Layer 7. Optional premium tiers exist for advanced Layer 7 filtering and custom rulesets, but the baseline is not an upsell.

With colocation the hardware is yours: you choose it, you own it, and you decide when it is replaced. We provide the space, the power, the cooling, the network and the hands. If you would rather not own hardware, look at dedicated servers instead.

In the United Kingdom, and we own it rather than rent space in it. It is operated as NorwichDC, and you can check the network from outside on our Looking Glass before you commit to anything.

Come and see the rack before you fill it

Tell us what you are installing and how much power it draws, and we will tell you which feed size you need and what it costs.
