Check HTTP request against reliable server

In my android app i keep getting timeouts in the messages between the app and my server.

In an attempt to see if the problem is in the app or my server,

i want to try and Send an HTTP request from my app to

some other server i am sure is up and reliable and then see if i get timeouts.

Is t开发者_如何学运维here any server address i can check against?

Thanks in advance!

BTW : i am using a glass Fish servlet for my server

We've successfully sent a simple HTTP GET to google.com -- with a couple of fall-backs (I've also seen internic.org used) in the past, in similar cases.
