When requests hang forever and recycling releases stuck work: why missing timeouts create backlog, how to add budgets safely, and the rollout plan that prevents new incidents..
Most production incidents do not start as "down." They start as waiting.
At 09:12 a dependency slows down. Your ASP.NET instances look healthy. CPU is fine. Memory is fine. But requests stop finishing. In-flight count climbs. Connection pools stop turning over. You scale out and it does not help because the new instances just join the waiting.
The cost is not subtle. Backlog grows, SLAs fail, and on-call starts recycling processes because it is the only thing that releases the stuck work. Then the incident repeats next week because nothing changed about the waiting.
