cURL no longer working

[belltown]

My web site uses cURL to retrieve data (business & restaurant listings, maps, directions, etc.) from other online sources (Google, Bing, Yahoo and Yelp). Everything was working well until the last couple of weeks when requests using cURL to retrieve data from external sources have been hanging, no data returned, no error code, just hanging. The same code works on my local server and on a couple of other free hosts.

Here's an example of code that is no longer working:

<?php
    
function getURL ($url) {

    if (($c = curl_init ($url)) === false)
        echo "Curl_init error: ".curl_error ($c);
    if (curl_setopt ($c, CURLOPT_RETURNTRANSFER, true) === false)
        echo "Curl_setopt error: ".curl_error ($c);
    if (($data = curl_exec ($c)) === false)
        echo "Curl_exec error: ".curl_error ($c);
    else
        echo "$data";

}

// This hangs ...
getURL ("http:/www.bing.com");

// This hangs ...
getURL ("http://local.yahooapis.com/LocalSearchService/V3/localSearch?".
            "appid=<my app id>".
            "&query=starbucks&latitude=47.6062095&longitude=-122.3320708&output=xml");
            
// This hangs ...
getURL ("http://api.bing.net/xml.aspx?".
            "AppId=<my app id>".
            "&Version=2.2&Query=sushi&Latitude=47.60881&Longitude=-122.338804&Sources=phonebook");
            
// This hangs ...
getURL ("http://api.yelp.com/business_review_search?".
            "ywsid=<my app id>".
            "&term=sushi&lat=47.60881&long=-122.338804");
            
// This works ...
getURL ("http://www.google.com");

// This hangs ...
getURL ("http://www.mapquestapi.com/directions/v1/route?".
            "key=<my app id>".
            "&from=SEA&to=BFI&format=xml");

?>

It seems that the only web site I can access now is Google. Attempts to access all other web sites hang.

Was there an announcement made that X10Hosting would be removing this feature that has previously been available on the free hosting plan? If so, I apologize for not reading it. If not, then I just wasted 3 hours of my time debugging my code trying to track down what was causing my web site to not work any longer.
