It seems as though Google has silently raised the API quota for Google Drive from 10 requests per second to 200 req/s.
The queries per day has remained the same at 1,000,000,000. However, the queries per 100 seconds has been raised to 20,000 from 1,000 (10 req/s).
Can anyone else comfirm whether or not this is a fluke or somehow non-standard to any google account?
