Unable to open Coursera JupyterLab
I can no longer access Courser JupyterLab: https://labs.cognitiveclass.ai/tools/jupyterlab/lab/tree/labs/DL0321EN/DL0321EN-2-1-Data-Preparation-py-v1.0.ipynb for the course https://www.coursera.org/learn/ai-deep-learning-capstone/home/welcome.
The error I receive is
"502 Bad Gateway
The server returned an invalid or incomplete response."

Looked like it couldn't resolve labs.cognitiveclass.ai (per Firefox status bar).
Also struggled with e-e186cfd01a.cognititiveclass.ai.Also took a few seconds to resolve widget.uservoice.com, but that step eventually worked.
