Looking for advice on handling 503 Service Unavailable errors when testing BYOC edge capacity. Running JMeter 5.6.2 from Singapore against the Genesys Cloud platform API. Ramp up to 100 concurrent threads targeting POST /api/v2/architect/flows for validation. Single thread works. At scale, the edge gateway seems to drop connections before the API layer. Any known limits on edge throughput for API calls versus media streams? Need to tune the load pattern.
