Community standard
Evidence before assumptions.
Good contributions are specific enough to reproduce, safe enough to share and honest about uncertainty.
- Sanitize everything.Remove customer names, public IPs, hostnames, credentials, secrets and identifying topology details.
- Describe the environment.Include relevant versions, topology, traffic direction and recent changes.
- Separate facts from theories.Label observed evidence, working hypotheses and confirmed root cause.
- Close the loop.Explain the fix, verification steps and how recurrence can be prevented.
