Yahoo YQL yahoo.finance.historicaldata returning empty results

I have developed and tested with the this API last week. Today I am noticing I am not receiving any results even from the sample query.

Anyone else experiencing this?

Solution

Unfortunately Yahoo! decided to discontinue their historical data API :-(

Hi All - This feature was discontinued by the Finance team and they will not be reintroducing that functionality.
