  13. Jupyter Notebook doesn't work again

    Hi,
    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)

  15. banned in error

    Hello,
    I was working on the Network Labs of Unit 3 of the course "Data Visualization with Python", when it stopped running the code. After restart the kernel, and later the site, a message appeareared telling me that I've been banned for "inappropriate activity".
    As I was acting properly, I would presume that a bug, mistake or connection issue had made this happen, so I'll ask you if can fix this.
    Thank you very much, I would like to keep learning this way :)

    The message says "If you think you have been banned in error, please open a support…
