A fault tolerant wireless system and method is disclosed that provides redundancy against a data center failure. Wireless connections are routed to a switch at a primary data center and forwarded through a gateway router, also located at the primary data center, to the internet. A backup switch and backup gateway router provides redundancy and are located at a backup data center geographically separate from the primary data center. The backup switch and backup gateway router provides an alternate path to the internet if the primary path fails. Both the primary switch and backup switch are assigned to the same subnet but the backup switch is advertised with an offset to favor routes through the primary switch.
