Service temporary unavailable when running "Create Glip Team Quick Start" example

I attempted to execute "Create Glip Team Quick Start" example in my IDE but it failed with Status Code 503 and message "Service temporary unavailable". Prior to running the code I made sure to login to https://glip-app.devtest.ringcentral.com/ with the same credentials used in the code.

What could be the reason for such transgression?
