After a long while, I finally managed to get a "Too many requests" error message in my regular course of browsing the site.
However, this message used to include a lot of error info, which the message prompted to include in emails sent to support regarding the limiting. When I got this error today, though, the message didn't include any error info, and simply stated I made too many requests. The styling is also completely different from how it used to be: the logo icon has been removed, and the page has almost none of the text formatting it used to have.
Why was the error info in the message for too many requests removed?
