It didn't work for me. It can't handle the spike in traffic right now that it reached the front page, that's probably what's going on.

Or its just badly developed. I hit question 4 and it failed.

Presumably many more people are taking the test. They should have just hosted this on whatever google sheets does with questionnaires. It seems a bit silly to want millions of people to take your quiz, but not have the resources available to serve it.
