Jupyter Notebook doesn't work again
When I open Jupyter Notebook from a Coursera course, I got 500 Internal Server Error.
It happens often and this is one of the most important parts of many courses.
Therefore I have three questions:
1) Is it possible to get a refund based on the fact that we pay for sth we cannot use?
2) When the issue will be resolved?
3) What availability can we expect (how many days a month it is expected to be working)
