A download or connection that times out once will usually succeed on a clean retry - the network blipped, your code did not change.

## What makes a failure safely retryable

Automatic retry is only correct for failures that are genuinely transient. Retrying a deterministic failure wastes minutes and hides a real defect, so the classification matters more than the retry mechanism.

- Safe to retry: network timeouts, registry 5xx, transient DNS failures, a service container that was not ready, a spot instance reclaimed mid-run.
- Not safe to retry: assertion failures, compile errors, lint violations, anything that fails identically on every attempt.
- Ambiguous, and worth investigating rather than retrying: out-of-memory kills, disk exhaustion, and flaky tests. These repeat under load and a retry only hides the trend.
- Always record that a retry happened. A pipeline that silently retries is a pipeline whose real failure rate you do not know.

## FAQ

### What causes Self-Healing CI: handling network timeouts and flaky connections?

A step that fetches dependencies, pulls an image, or calls an external service fails with a connection timeout or reset. Re-running the job resolves it with no code change.

### How do I fix Self-Healing CI: handling network timeouts and flaky connections manually?

[object Object]

### Can Self-Healing CI: handling network timeouts and flaky connections be fixed automatically?

Timeouts and connection resets carry a recognizable signature and a safe default response - retry with backoff. A self-healing pipeline detects the transient failure and retries automatically, surfacing the step only if it keeps failing, which is the signal that the problem is real rather than a blip.
