When I use the Google calendar API to create a new Calendar, I randomly get "Backend Error". Do you have any idea why ? Have you experienced the same behavior ?
First request :
POST https://www.googleapis.com/calendar/v3/calendars Authorization:
Bearer ya29.UQEd-xxx
Content-Type: application/json; charset=utf-8
{"summary":"My new calendar name"}
Google answer (around 20 seconds later):
{ "error": { "errors": [ { "domain": "global", "reason":
"backendError", "message": "Backend Error" } ] "code": 503, "message":
"Backend Error" } }
The calendar is not created
Another request :
POST https://www.googleapis.com/calendar/v3/calendars Authorization:
Bearer ya29.UQEd-yyy
Content-Type: application/json; charset=utf-8
{"summary":"My new calendar name"}
Google answer (around 5 seconds later) : 200
The calendar is created
503 Service Unavailable
The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
503 is a standard HTTP error that happens sometimes. Google ops probably has a graph somewhere showing the frequency of the errors and depending on their priorities may be working to fix it. You should catch the error and either give a human the chance to retry or implement exponential backoff.
Google Apps Calendar Resource API Limits and Quotas
For all errors that are time based (maximum of N things for N seconds per thread), especially the 503 status code errors, we recommend your code catch the exception and, using an exponential backoff algorithm, wait for a small delay before retrying the failed call.

Yes google calendar services are currently unavailable. Confirmed from twitter.
