Give students the code in .ipynb files to store locally rather than hosting them in a faulty cloud service
- This service is being paid for
- Your Jupyter Notebooks service is often down
- The course is paid for on a monthly basis (Time = Money)
You should provide the .ipynb files for student to store on their own device to complete lab sessions
Respond to user queries/ Get it fixed quick
Refund everyone for the time the service is down/intermittent.
Provide the service at no cost.50 votes
