I have been using the Heroku CLI for some time now without incident. Shortly after deploying a batch of new code today, it became totally unresponsive. When entering a command (e.g. heroku status) it just hangs forever. Doesn't matter what command I enter, it hangs. I've restarted my terminal and also tried killing the Heroku CLI process a few times, but the problem persists.
How can I debug the problem? Is it my installation or is it a Heroku problem?
