Zero-Downtime Network
The Rackspace network has been engineered from the ground up to accommodate the high-availability demands of our customers' mission-critical Web applications. Our Cisco-powered, Zero-Downtime Network™ has unique self-healing attributes that allow us to deliver on our 100% infrastructure availability guarantee.
Rackspace doesn't rely on any single connectivity
provider. Instead, we employ a multi-provider strategy.
This offers benefits over simply partnering with one
network carrier. Working with multiple network carriers
creates natural redundancy in our network architecture
and ensures that packets can leave our network from
multiple points. Additionally, if one or more providers
experience congestion or downtime, traffic can be
rerouted through other network partners until the
issue is solved.
Beyond simply providing redundancy in case a particular provider experiences downtime, our proprietary networking technology allows our network operations team to actively probe the public Internet for packet loss and latency and automatically reroutes traffic around these areas. This ensures that traffic leaving the Rackspace network is not bound for a part of the public Internet that is heavily congested.
Guaranteed Packet Delivery
Our providers are paid to make sure that packets of information are delivered quickly and efficiently to your end users. This offers significant advantages over simply peering with the major backbones. Peering agreements rarely include Service Level Agreements (SLAs) so no one is accountable for lost packets at congested exchange points. Because Rackspace has SLAs with all of our network partners, we are able to guarantee that all packets will leave our network at full speed.
Bandwidth Utilization
Rackspace substantial bandwidth capacity allows us to accommodate even the largest spikes in traffic. To ensure rapid delivery of content, we continuously add network connectivity and new routes. Low bandwidth utilization allows for maximum uptime, even if multiple transit partners experience simultaneous outages.
Network Providers
Rackspace works closely with leading telecommunications
providers to build and maintain our world-class network.
