# MathJax CDN (cdn.mathjax.org) will be shutting down

The news that MathJax CDN shutting down on April 30, 2017 was recently brought to my attention. I have updated ChatJax to use the alternate server given in the MathJax post. It seems to work well, but if StackExchange is going to host a local copy to use with the sites that support MathJax, I will update ChatJax to use that server instead.

Have any SE developers seen this news, and if so, what are the SE plans for continued support of MathJax?

• Stackoverflow devs were naturally the first to hear from us at MathJax on this matter. – Peter Krautzberger Apr 1 '17 at 17:22
• Would you mind posting this (instead or in addition) on the main meta? By now quite a number of SE sites use MathJax, and this is thus more widely important issue. – quid Apr 1 '17 at 17:23
• @quid: I have reposted this here. – robjohn Apr 1 '17 at 18:00

If $f(x) = e^{-x^2}$, then $f'(x) = -2x \, e^{-x^2}$ and $$\int_{0}^{\infty} f(x) \, dx = \frac{1}{2}\sqrt{\pi}.$$
