From @Negin Sobhani over in the NHUG slack:
Hello Everyone, We are currently experiencing issues with the NCAR/UCAR JupyterHub slow response due to the sudden traffic of users (CESM tutorial, ASP workshop).
We apologize for this issue. In the meantime, please feel free to use the old method of contacting JupyterLab which should work fine : https://arc.ucar.edu/knowledge_base/70549894#JupyterandIPython-StartingJupyterLab
