503 Service Unavailable after multiple calls

I have a list of addresses that I'd like to map out. I decided that I would iterate through this list; each time calling the Yahoo Local API and storing the lat/long results. If I make 1 call to the API....it works fine. But, if I attempt to make many calls, one after the other, I get this error:

"failed to open stream: HTTP request failed! HTTP/1.1 503 Service Unavailable"

Once I get this error, I can't even make single calls anymore. It seems that I am being blocked from calling the API after attempting to access it multiple times in repetition. My request string is formed correctly. If I copy and paste a request into my browser to test the call I get this:

"The following errors were detected: backend fetch error 999"

the request looks like this:

http://local.yahooapis.com/LocalSearchServ...a&results=1


I'm not breaking the 5000 query limit but I'm also not a very seasoned PHP dev either. However, I don't think the issue is with my PHP code as the call doesn't even work in the browser. If anyone could help me with these errors I'd really appreciate it. Thanks!

  • Yes, it seems typical Yahoo problem. I'm also calling API sending requests one after another even from uniq IP and stumble with this error.
    Did you manage with it?

    P.S. Yahoo, please do something!
