I've just pushed a new version of SRFI 122 that updates the
document to account for the shutdown of the MathJAX CDN.
The SRFI 122 document uses MathJAX to format its
mathematical notation, so it was necessary to move to a new
CDN (or host MathJAX on the SRFI site, which I chose not to
do).  No visible changes to the document should be apparent.

See <https://www.mathjax.org/cdn-shutting-down/> for
details on the shutdown and recommended actions.

Regards,

SRFI Editor
