The Yahoo YQL queries seem to return no results since two days. However, trying to find the cause is difficult as it works very very rarely using the YQL Console.
Browsing through their forums and the net it seems that it happens once in a while and might be some load balancer bug as it happens only in some geographical regions.
Anyways, to not be dependent on such random outages that persist for quite some time implement the YQL queries yourself or use a different library or service and replace YQL.
