Abstract
A system is configured to receive, by a first server, a request, from a user device, for a first record stored by a cache associated with the first server, determine, a first timestamp associated with the first record, determine that the first record is invalid based on the first timestamp, and determine, based on determining that the first record is invalid, whether the first record is out of date with respect to a corresponding second record stored by a second server by comparing a second timestamp of the first record with a timestamp of the second record. The system is further configured to update the first record with information from the second record to form an updated first record when the first record is out of date, and to send the updated first record to the user device associated with the request.
