Looks like the math service (Mathoid) isn't running on beta.

I confirmed Mathoid is running on deployment-mathoid.deployment-prep.eqiad.wmflabs (IP: 10.68.20.104):

$ netstat -nlp | grep 10042
tcp        0      0 0.0.0.0:10042           0.0.0.0:*               LISTEN      29929/nodejs

Perhaps a configuration issue?

While trying to save a page with the <math> tag, I got:

Smells like a cache invalidation issue. @aaron, got any thoughts on this?

Did that fix the issue? I also changed this to not a Beta Cluster itself issue, but something you found in BC.

Mathoid is working now. Still getting an exception but that's a VE issue.

Confirmed. Math and Mathoid are working properly in BC.
