Flash Yahoo Maps has stopped working?

In the past week it appears that Yahoo has changed their crossdomain file to only accept Yahoo domains (http://maps.yahooapis.com/crossdomain.开发者_高级运维xml):

This is causing my applications that use Yahoo Maps to stop working (i.e. security exception). I cannot proxy the calls to Yahoo because the URL is embedded in the MXP file that Yahoo distributes. Does anyone know if there's a workaround or update to this?

Interestingly Yahoo's own examples on the following page aren't working right now either: http://developer.yahoo.com/maps/flash/asGettingStarted.html
