Details of our Servers & Network

Servers

All of our servers are housed at Centro, based just outside of the M25 in Hemel Hempstead. The datacentre boasts exceptional facilities, high security and a fantastic record for reliability.

UK based datacentre facility High security area featuring CCTV and secure fencing Biometric mantrap entry to the data floor Rows of locked colocation racks Fire suppression system Power distribution Units Temperature and climate control units

The facility has been fitted out to a high specification, with all infrastructure installed with a minimum of N+1 redundancy, and certain key elements at 2N. A state-of-the-art IP CCTV system and access control system form part of the comprehensive security arrangements, including man-traps, interlocked doors, and biometric iris scanners.

Our datacentre operators are a member of The Green Grid industry body, comply with the European Code of Conduct for Datacentre Operators best practice guidelines, and have been externally audited and certified to ISO 9001 (Quality Management), ISO 14001 (Environmental Management) and ISO 27001 (Information Security) standards.

The facility achieves a PUE figure of between 1.2 and 1.4 without using outside air for cooling. The same facility is used by Spotify, Verisign, Adobe, Symantec and many more.

Network

Network uptime and speed are critical elements to any web hosting provider and can often ‘make or break’ a hosting company. We are proud to have all servers connected to the internet using a fully redundant network which has provided us with excellent uptime during the 8+ years we have used it.

Some key features include:

  • Fully diverse Juniper MX routing network.
  • Fully diverse Juniper EX core switching network, diverse HP access switches.
  • 100% infrastructure uptime SLA
  • Transit - 40gbps to NTT, 40gbps to GTT, 20gbps to Global Crossing/Level3
  • Peering - 20gbps to LINX, 10gbps to Virgin Media, 4gbps to Lonap, 4gbps to AMS-IX, including various other private and public peers (BT, Talktalk, Sky, etc)
  • 300km DWDM dark fibre network Spanning our 4 Gyron DCs and 3 carrier neutral facilities
  • Dual redundant gigabit feeds to each rack
  • Peers including Microsoft, TalkTalk, Pipex, Cogent, Virgin, Claranet, Google, HE, Akamai, the BBC, and hundreds more

Back-Up

All data is held on a secure server and automatically backed up to another physical location on a twice daily basis whilst static web pages are backed up weekly. Our restore exercises have indicated that in the event of a corruption we would be live again within 2 hours.

In addition we keep our DNS information at a third location so that in the event of a complete failure at the Hosting Centre we would be able to mount our entire system at our alternative location very quickly although we would of course be limited by the speed of propagation of the DNS information over the internet.
