I'm guessing that many folks here are aware that the MathJax CDN has recently shutdown; the official information is here:
https://www.mathjax.org/cdn-shutting-down/The Jupyter Notebook appears to use a local copy of MathJax but notebooks exported via nbconvert seem to point to the old MathJaX CDN. There is a temporary redirect that allows this to work for the time being, though not as efficiently as it should. The recommendation is that most HTML pages should point to a copy of MathJax on CloudFlare. Is there a plan to make this happen? I don't see any discussion of it on this list?
For the record, I'm using Jupyter installed via Anaconda on my Mac. Before posting this, I ran
> conda update notebook nbconvert
so that I get the following in the notebook:
import notebook, nbconvert
print(notebook.version_info, nbconvert.version_info)
# Out: (5, 0, 0) (5, 1, 1)
