Is linuxjourney.com down for anyone else?

It says “An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail”

EDIT: nvm, heroku is a cloud service, so most likely it’s down for everyone. Hope the website gets back up.

EDIT2: the github repo includes all the lessons (https://github.com/cindyq/linuxjourney)
