Abstract: A method performed by a health service configured to update a domain name system (DNS) to enable clients, which use the DNS, to allocate service requests to a plurality of service instances which provide the service wherein each service instance comprises a microservice architecture is presented. The health service requests outcome data from at least one of the service instances, and calculates a status indicator for the service instance, wherein the status indicator is calculated based on results from internal recursive checks performed throughout the microservice architecture of the service instance and heuristic calculations performed on service request performance data. After calculating the status indicator, the health service triggers a dynamic update to the DNS according to the calculated status indicator.
