YQL weather result is zero 1.5 times

Question

Yahoo data sometimes cannot receive data, "query.results is null or not an object."

This happens to me on Chrome 55.0.2883.87 and fierfox 50.1.0.

This is the YQL I am using:

http://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast, where woeid = 2514815 & format = json

And the answer is:

{"query": {"count": 0, "created": "2017-01-01T22: 27: 51Z", "languages": "Results" "EN-US": NULL}}

What am I doing? ideas?
