Cloudflare alt-svc onions cause a different exit to be used at each request
For some websites, such as zerobin.net which use Cloudflare's new onions, each request might cause a different exit to be used. This is bad both from a load perspective as well as a fingerprinting perspective.
Steps to reproduce: Go to zerobin.net and create a new paste with "allow discussion" enabled. Post several comments and observe that the visual hash of the IP often changes with each comment. Check the circuit display to verify.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
