503 Error Service Unavailable

[Alonreznik]

Hi there. 

Since yesterday, when we're trying to upload data from our servers into google cloud storage buckets (internal or external), we're getting the next issue:

"<HttpError 503 \"Service Unavailable\">"

We can't identify any statuspage incidents, but we identified a 503 errors on BQ discovery service in our service health in GCP.

Please advise,

Thanks!

Hello @Alonreznik!

Welcome to the Google Cloud Community!

You can do the following troubleshooting options:

1. The 503 error from BigQuery says that there is a temporary server failure such as a network connection problem or server overload. What you can do here is wait for a few seconds and retry again, if the problem recurred, retry with exponential backoff.
2.  Check out Cloud Storage Monitoring. Here you can monitor requests to Cloud Storage including tracking errors, request rates, and data usage. You can track the server error rate which are requests with 5xx error codes. These errors are generally caused by issues internal to Google Cloud. Such errors are both retryable and applicable to the Cloud Storage SLA.
3. If the above options don't work, you can contact Google Cloud Support to further look into your case. Let me know if it helped, thanks!
