Cwazy has servers on two sites.

Redbus in London & IFL1 in Manchester.

Almost all our email is run from Redbus in London.
Our London server is a 64bit 2Ghz server with 2GB of ram and a 200GB raid array.

We are connected via a BGP routed network using fully redundant Cisco GSR carrier class routers.
The network has two connections to Level(3) communications & is also connected to Teleglobe, Enta, Euroconnex, Express, Packetexchange, TSN and (in case of emergency) Cogent.
Redbus has 24/7 on-site personnel for security, security barriers & CCTV surveillance.

The site has power to an N+1 standard; put simply, this means that if two generators are required to provide non-stop power, then there'll be three installed.

Amongst other things, the site also has Very Early Smoke Detection Apparatus (VESDA) installed.

Our servers in IFL1 are similarly protected and used for web hosting.
