we are getting today a "Service Unavailable" response (with status 500) from Google APIs, in particular for the following call
POST https://www.googleapis.com/upload/analytics/v3/management/accounts/<ACCOUNT_ID>/webproperties/WEB-PROPERTY-ID/customDataSources
Looking at Analytics service status at seems the service is up & running.
Do you know if something is changed from yesterday?
Our calls are done via scheduled job on a daily bases and yesterday they were responsive
