Afraid Cloud9 is currently having an issue whereby the IDE is failing to connect to hosted workspaces. They're currently investigating, so we're hoping it will be resolved shortly. In the meantime, if taking CS50's on-campus quiz, consider focusing on question 4 (To be or not to be) and question 5 (Vantage Points), which don't require writing code.
