1. A method, comprising:
receiving, by a first server system located in a first one of a plurality of network regions, a request from a first user to perform a first operation with a second user, wherein the request includes an alias value for the second user;
determining, by the first server system based on the alias value, that the second user is not associated with the first network region;
accessing, by the first server system, an alias map that specifies encoded versions of alias values that are in use across the plurality of network regions, wherein the first server system does not have access to a subset of alias values associated with users associated with one or more of the plurality of network regions;
determining, by the first server system, that the second user is associated with a second one of the plurality of network regions, wherein the determining includes:
generating a first encoded value based on the alias value;
comparing the first encoded value to the encoded versions of alias values specified in the alias map; and
determining that the first encoded value matches a second encoded value in the alias map, wherein the second encoded value is associated with an identifier for the second network region; and
routing, by the first server system, a first communication corresponding to the request to a second server system that is located in the second network region.
