Outage Details

After upgrading our S3 gateway, we encountered a problem on buckets with CORSConfiguration with a value of "*" in their AllowedHeaders. In this particular case, the CORS preflight request does not return the `Access-Control-Allow-Headers' header and fails the validation. If you have a CORS configuration on your bucket with the value AllowedHeaders: *, the CORS preflight request will fail for all headers. We plan to roll out the fix tomorrow and deeply apologize for the inconvenience.
