1. A system comprising:
a primary point-of-presence (POP) group of servers including multiple server pools in different geographic locations, each server in the primary POP group being reachable at an address of a first internet protocol (IP) address block and configured to serve content of a domain;
a secondary PoP group of servers, each server in the secondary POP group being reachable at an address of a second IP address block and configured to serve the content of the domain; and
a traffic management agent stored in memory and configured to reduce a total volume of incoming requests received by the primary POP group for a period of time following a return of a first POP server pool in the primary PoP group of servers to an online state by selectively directing a first percentage of the incoming requests to the second IP address block instead of the first IP address block, and wherein the traffic management agent gradually decreases the first percentage of incoming requests directed to the second IP address block as time passes following the return of the first POP server to the online state.
