Systems, methods, and computer program product are disclosed for providing a mechanism for re-routing queries in a telecommunications network. A service control point (SCP) executes an application which causes queries to be launched over a LAN or WAN to a remotely located data center. Primary and secondary data centers are defined, in which the secondary data center operates on a 'hot-standby' basis. Based on an automatically verifying system, the detection (or lack thereof) of a response from a primary data center and comparison of the response against an answer or response from another site indicates whether or not the SCP or SCP application should route queries to the secondary data center. Similarly, the same mechanism can be used to indicate that queries should be re-routed back to the primary data center.
