I first noticed this a while back. But it has yet to resolve itself.
When I click on the post feedback link in the 10k tools, it hangs for a while.
Then it gives me an error message:
Meta Stack Exchange is a question and answer site for meta-discussion of the Stack Exchange family of Q&A websites. It only takes a minute to sign up.Sign up to join this community
It only took a little over 5 years for me to get around to fixing this, but this link has been put back under
/tools and the page should be loading again.
I spent a bit of time yesterday looking at the Post Feedback page and tried to optimize the queries. After refactoring things a bit, the query now runs in about 10 seconds versus the original 30-40 seconds that resulted in the time-out on that page. I'll monitor the performance on Stack Overflow and see if I need to make any more changes to help that page along.
The way this is architected absolutely does not scale. It's also not something we want to put resources into fixing given opportunity cost and what it would take to refactor.
We will be removing the link in the next build and removing the page and code later in the week. I'm sorry that answer sucks, but it's just not an important feature to us, and it would take a significant time investment to fix.
This link still finely works anywhere, except Stack Overflow.
So, whatever reasons were to disable it, the page is still accessible there on any Stack site (works on beta site for me; confirmed to work on Meta; for me on other sites excluding SO (which gives "not found") and LH (which fully works, because I have required rep there) the page says "more privileges required").
