# Self-Healing CI: Auto-Retrying an Artifact Upload Timeout

> An artifact upload that times out is a transient transfer problem, not a build failure. See the manual fix and how self-healing CI retries the upload automatically.

An artifact upload that times out is a network problem on the way out, not a problem with the build that produced the artifact -- a retry usually completes it.

## 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 an artifact upload timeout?

An artifact upload step fails with a timeout or reset while transferring build output to the artifact store. The build succeeded and the files are valid; the upload hit a transient network or backend slowdown. A human re-runs the job and the upload completes unchanged.

### How do I fix Self-Healing CI: Auto-Retrying an artifact upload timeout manually?

[object Object]

### Can Self-Healing CI: Auto-Retrying an artifact upload timeout be fixed automatically?

An artifact upload timeout has a recognizable transient signature, and the safe response is to retry the transfer. A self-healing CI pipeline detects the upload failure, retries with backoff, and only escalates if the upload keeps failing, distinguishing a momentary transfer problem from a genuinely unreachable artifact store.
