[gdal-dev] 503 Errors when accessing Public Datasets on Google Cloud Storage with automatic auth

Wed Oct 16 08:20:55 PDT 2019

Hi,

When doing a few requests to the Sentinel 2 bucket of Google (
https://cloud.google.com/storage/docs/public-datasets/sentinel-2) we have
been getting 503 Responses when using the automatic authentication. See the
end of this email for the full output.

This behavior goes away when using e.g. the
GS_ACCESS_KEY_ID/GS_SECRET_ACCESS_KEY authentication method.

The Service account this machine is running with has "Full Access to All
Cloud APIs"

Not sure if this is a gdal problem or actually a google internal issue
since accessing our own buckets works fine.

Best,
Christoph
