# Self-Healing CI: Auto-Retrying a Yarn Network Timeout

> A Yarn install that times out fetching a package is a transient transport blip, not a missing dependency. See the manual fix and how self-healing CI retries it.

A Yarn install that times out fetching a tarball hit a congested registry moment, not a broken dependency -- the same install completes on a retry.

## 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: Auto-Retrying a Yarn network timeout?

A yarn install fails with a network timeout while fetching a package tarball or metadata. The package and version exist and the lockfile is valid; one of many fetches hit a transient network problem. A human re-runs the job and the install completes cleanly.

### How do I fix Self-Healing CI: Auto-Retrying a Yarn network timeout manually?

[object Object]

### Can Self-Healing CI: Auto-Retrying a Yarn network timeout be fixed automatically?

A Yarn network timeout carries a recognizable transient signature -- a timeout on a fetch, not a missing-package error -- and the safe response is to retry the install. A self-healing CI pipeline detects the failure, retries package resolution, and only escalates if a package is genuinely unavailable, distinguishing a slow registry
