I used the Opam Weather Service in the past, but it seems to be no longer available.
I had the impression that a similar system was still available somewhere, but I can’t find it (maybe it was just one of @AltGr’s presentations?). I’d like to be able to get an overview of which builds are broken, e.g. for older packages so that I could try to add proper constraints to them, and prevent opam from occasionally finding exotic combinations when I’d like it to find none.
Is there currently a way to see which packages are broken, other than by uploading a new one to
