We have a bot that we developed to be only internal. It is based on hubot and uses this adapter: https://github.com/tylerlong/hubot-glip
The bot worked great for 10 months or so, but just stopped working. We haven't changed anything. It looks like it subscribes to get notified for posts just fine... but it never receives anything. Did something change?
It is still working in the Sandbox environment (where we also haven't made changes).
