# Self-Healing CI: Auto-Retrying a NuGet Restore Network Blip

> A NuGet restore that fails on a network blip is a transient transport problem, not a missing package. See the manual fix and how self-healing CI retries the restore.

A NuGet restore that fails partway hit a network blip on one of many feed requests, not a missing package -- the same restore 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 NuGet restore network blip?

A dotnet restore / nuget restore fails because a request to the package feed timed out or reset mid-download. The package and version exist; one of many feed requests hit a transient network problem. A human re-runs the build and the restore completes cleanly.

### How do I fix Self-Healing CI: Auto-Retrying a NuGet restore network blip manually?

[object Object]

### Can Self-Healing CI: Auto-Retrying a NuGet restore network blip be fixed automatically?

A NuGet restore blip carries a recognizable transient signature -- a timeout or reset on a feed request, not a missing-package error -- and the safe response is to retry the restore. A self-healing CI pipeline detects the failure, retries package resolution, and only escalates if a package is genuinely unavailable, distinguishing a
