What do you actually check in the first 15 minutes after deploy?

CI passed. The deploy finished. Nothing is obviously broken. And yet, for a few minutes after release, production still feels uncertain. I think this is one of the most awkward parts of shipping software. A deployment can be technically successful: build passes tests pass pipeline passes container starts health checks look fine But real runtime problems can still show up only after actual traffic hits the system. That creates a weird gap between deploy success and runtime confidence. The part that still feels manual In a lot of smaller teams, the first few minutes after deploy still look something like this: open logs check recent exceptions watch for error spikes compare current noise with what “normal” felt like before decide whether to ignore, investigate, or rollback We have plenty of tools for detection. We can detect: exceptions timeouts retries latency spikes failed external API calls degraded endpoints But detection is not the same as judgment. The real post-deploy question is
