Claim 6:
7. Non-transitory computer-readable media comprising computer-executable instructions that, when executed on a computing system, cause the computing system to:
analyze health information for a network-accessible service to detect that plurality of cell systems implementing the network-accessible service are in a healthy state, individual cell systems comprise one or more computing devices configured to implement the network-accessible service on behalf of corresponding portions of clients;
while each cell system of the plurality of cell systems is detected to be in the healthy state, initiate a set of migrations of at least a portion of a workload from one individual cell system, selected from the plurality of cell systems independently of load on the one individual cell system and at least partly at random, to another individual cell system, selected from the plurality of cell systems independently of load on the other individual cell system and at least partly at random;
analyze additional health information for the network-accessible service to detect that at least one cell system implementing the network-accessible service is in an unhealthy state; and
responsive to detecting that the at least one cell system implementing the network-accessible service is in an unhealthy state, halt the set of migrations.
