Techniques described herein relate to automatic upstream service resumption after downstream system failure. An automatic resumption module may be configured to monitor a downstream endpoint (of a problematic downstream service provider) and determine when it again successfully can process requests by periodically processing inbound requests (e.g., from suspended upstream service providers) and automatically re-enabling upstream endpoints for the suspended upstream service providers in the case of success. The automatic resumption module may start a trickle feed timer for each upstream endpoint to allow messages to be processed at a configured retry rate while the upstream endpoint remains suspended. The trickle feed timer may be configured to start upon the triggering of a circuit breaker for the involved downstream service. When downstream endpoint invocation succeeds, the automatic resumption module can resume all upstream endpoints associated with the downstream endpoint.
