A bypasser configured to operate within a three tiered synchronization system. The bypasser can include an interceptor and an inference engine. The interceptor can intercept synchronization requests before a synchronization event involving a synchronization server is initiated. The inference engine can determine if the data store and the another data store are to be synchronized and can selectively initiate the synchronization event based on the determination of the inference engine. For example, when the inference engine determines that synchronization is not to occur, the bypasser can convey a notification that no update is needed to the source of an intercepted synchronization request without requiring the synchronization server to process the synchronization request. When the inference engine determines that synchronization is to occur, the bypasser can convey an intercepted synchronization request to the intermediate synchronization server for processing.
