Network Redundancy

Return to FAQ/Help System menu

Our network is comprised of redundant backbones and servers diversely spread across the USA and the United Kingdom.

We utilize connections to multiple backbones to ensure that data reaches the end-user in the fastest, most efficient manner possible. We also have peering agreements with local ISPs to allow fast delivery of packets when possible.

BGP4 Routing
We run the Border Gateway Protocol (BGP4) for best case routing. Our entirely switched, Cisco powered network employs Cisco GSR 12000 class routers running HSRP (N+1 hot failover) to ensure that data can be routed even in the event of a router failure. The BGP4 protocol is a standard that allows for the routing of packets of information sent out from the Rackspace Network. Each packet of information is evaluated and sent over the best route possible. Because of our redundant network architecture, packets may be sent via alternative routes even if they are being delivered to the same end user. Should one of our providers fail, packets leaving our network are automatically redirected through another route via a different provider.
