| ## error_rate |
| |
| An elevated error rate likely indicates some problem communicating with GCS, |
| which may point to a configuration problem or some transient problem with GCS |
| itself. The CDN service may also log errors for bad requests, eg. when an object |
| is requested which does not exist. This may be caused by an individual user |
| making a mistake or by misconfiguration of another service. Check the |
| [logs](https://pantheon.corp.google.com/logs/query;query=resource.labels.container_name%3D%22cdn%22?project=skia-public) |
| and determine the root cause. |
