IP Transit

We can present our own (AS 50300) impressive fully multi-homed BGP IP Transit network to each rack on two diverse 1Gb ports, which run out of separate switches on our network. Both of these are on the same network, but are from different sources to ensure connectivity continues if one of your feeds were to go offline. To prevent network storms, we have enabled Spanning Tree Protocol (STP) for your links with the A feed taking priority. Bandwidth, like power, is available to fit your requirements and is billed on 95th percentile. As a carrier neutral data centre, we also present other network providers.
