MathJax CDN service at cdn.mathjax.org has been retired

[Peter Krautzberger]

Hi,

We would like to remind you that we have retired our CDN service provided at cdn.mathjax.org on April 30, 2017.

The redirect we put in place (redirecting from cdn.mathjax.org to cdnjs.cloudflare.com) is working as expected and should give most users more time to switch to one of the available alternatives. 

If you have not yet switched away from cdn.mathjax.org, we urge you to make the switch as soon as possible. The announcement https://www.mathjax.org/cdn-shutting-down provides several alternatives.

Thank you for your interest in MathJax.

Peter for the MathJax Team.
