Error 404 for http://widgetserver.com/proxy/ws_proxy.js

Hi,

I just tried to continue development on my widget when I noticed that the Javascript-API function WIDGETBOX.net.ProxiedHTTPRequest() doesn't work anymore (I use this for requesting external RSS-feeds): The requested URL http://widgetserver.com/proxy/ws_prox...[whole amount of parameters] returns an error 404

Yesterday everything worked o.k. Are there problems at the moment? If so: when will this be fixed? Unfortunately I'm in a bit of a hurry...

Thank you!
