That project is a great find, thanks! A real time saver, I should have these marked up shortly.
I’ll do some more thinking on how we represent Cloudflare instances in general, I think for the time being I may just include a short note for them as people will wonder why they’re marked anyway.
Edit: This is now done, all Cloudflare instances marked and an explanation added.
Awesome project and the tool looks great - nice work!
There was an existing tool which was similar: https://federation-checker.vercel.app/
Yours is definitely nicer.
