All ionic codepens non-functional for me

I’m reluctant to post this here, because it seems so unlikely. But went try out, say, a nightly ionic codepen (like: http://codepen.io/ionic/pen/mqolp), I get basically nothing. If I bring up the console, I’m seeing these errors:

GET http://code.ionicframework.com/nightly/css/ionic.css net::ERR_CONNECTION_TIMED_OUT

GET http://code.ionicframework.com/nightly/js/ionic.bundle.js net::ERR_CONNECTION_TIMED_OUT

Uncaught ReferenceError: angular is not defined

Any embedded codepens are showing up blank for me as well. Any ideas?

Some type of firewall issue here. Unfortunately, I’m not sure how to fix it. Good news is it works everywhere else…

finally i found the fix
