Hello everybody

I have an application that using YQL returns words suggestions (Did you mean?).
All right until a few days ago I only get the following error :
   
    http-status-code":"999",
    "http-status-message":"Unable to process request at this time -- error 999".

The documentation suggests that the error is due to Yahoo's services are saturated. I've found on forums that could be because I have exceeded the number of requests but I can say that this is not the case.

    url : http://query.yahooapis.com/v1/yql
    query : ex: select * from search.spelling where query="query" and appid="appid"

I tried giving me high in the Yahoo Search BOSS but the problem persists. (http://boss.yahooapis.com/ysearch/spelling/v1/rebolucion)

I have also found that queries through the console (http://developer.yahoo.com/yql/console/) work correctly but if I run in the browser the query
generate in the THE REST QUERY I get the same error
