Unfortunately the reverse geocoding services I provide is down as there are too many incoming request. This resulted in Yahoo services blocking the requests coming from my servers. When I wrote this service I never thought that it would be so popular as I wrote it has some sort of hack. But a few month done the line and there are about 500 000 requests per month.
If you are still interested in reverse geocoding your long/lats I published the source code used for the reverse geocoding service in github http://github.com/geomojo/ReverseGeocoder.
The recommanded solution for reverse geocoding to WOEID is by using the Flickr API flickr.places.findByLatLon.html
This can also be done using the YQL language:
Where the lon and lat parameters contains the lat/long you want to reverse geocode into a WOEID.
