A customer of a computing resource service provider submits a request to a service in a first data region to obtain all customer data stored across all data regions managed by the computing resource service provider. Accordingly, the service may refer to a chatter table that includes a listing of locations wherein customer data may be stored to determine which data regions comprise customer data. Based on the determination, the service may transmit one or more requests to other services within the determined data regions to obtain the customer data while ignoring any data regions that do not comprise customer data. Upon receiving the customer data, the service may aggregate this data and provide the aggregated data to the customer to fulfill the customer request.
