"Too many redirects" is the result of a self-referencing link, usually caused by poorly coded advertisement.
So how to fix that darn page!
Only the website developer can do that. Often, they will plead ignorance and blame the problem on an advertisement or some other content hosted by that webpage for "revenue enhancement". That's a poor excuse. My webpage suddenly isn't working - ERR_TOO_MANY_REDIRECTS message illustrates one such example the website developer needed to address.
What can you do? Content blockers (ad blockers) can help, but none are completely effective and they can result in unintended consequences.
The bottom line is that you can't fix someone else's webpage.
What's the definition of too many?
Good question. As far as webpage development standards go there is no absolute predefined upper limit, but whatever it happens to be Safari decided it was too many and that there would be no point in continuing down that path.

This led me to question just how many redirects is considered too many. The answer is that different browsers impose different limits. The generally accepted answer is that ten redirects are ok, but twenty is definitely too many. The reason for the limit goes beyond page loading efficiency. It is one of several defenses against various means of implementing tracking.
There are several ways of accomplishing a redirect; this WebKit reference describes one such defense:

By the way I just tired loading that same page and got the same result:

The webpage is defective.
