  5. My idea is that you figure out how to fix a website after three days of being down.

    What in the heck am I paying $39 a month for, along with everyone else here, if you're just going to break your website for days at a time? Also, turn off the grading requirements for the time being so that we can just complete our courses and get our certificates. Like seriously, do anything.

  6. Unable to "Open Tool", Start Lab Environment to open Jupyter Notebook - Databases and SQL for Data Science with Python

    I am currently unable to load the Jupyter Notebook. When I click on the "Open Tool" button for the Peer-Reviewed Assignment on week 5, it brings me to a page with "Please wait while we prepare to start your lab environment." and a loading circle. It loads for very long (might have been more than an hour) and does not come up with an error message. I have tried using different browsers, cleared my cookies, used incognito mode, and changed my internet connection. It still does not work. Please help. Thank you.

  16. Unable to access Jupyter notebook in Cognitive labs examples from Coursera

    Hi, I cannot access Jupyter Notebook in the Skills Network virtual lab environment available through Coursera. Looking at the other posts, I reckon it's not an issue just for me. Plese fix. Thank you.

  17. 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)

  19. 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…
