I hopped on to work on my project but nothing is showing up to be able to test my project. I clicked the original link and there is nothing there either. Please advise.
It looks like the external resources have been blacklisted. I have created a GitHub Issue here which you can follow.
Wow! Codepen is tightening the reigns. Thanks for the quick work on that!
It’s not CodePen that’s blocking it, but the service that FCC is using to externally link their testing repository. Poking around a bit it looks like this is triggered automatically by too many error responses.
ETA: The good news is that I have a hunch this can be fixed quickly, so go ahead and work on your project and by the time you’re done the testing might be up and running again.
