It looks like that last run was in 2025…

I was wondering the same a few weeks ago on Discord, but got no replies.

The whole website is very slow to load as well: the results table only loads packages starting with a-c.

The jobs have been failing to create the appropriate switches so the runs have been failing. I’ve resolved this now and a new run is in progress with a reduced set of compilers matching opam-repo-ci. Check back in a few days but which time the run should have finished.

Currently website is missing compiler 5.1 and 5.3. Is it intentional?

Yes. The tested versions match the versions tested by opam-repo-ci. opam-repo-ci tracks “significant” versions. See [ocaml-version/ocaml\_version.ml at de164f480705dd214cd406bbd762d3da2d3612b5 · ocurrent/ocaml-version · GitHub](https://github.com/ocurrent/ocaml-version/blob/de164f480705dd214cd406bbd762d3da2d3612b5/ocaml_version.ml#L257-L261)

It would be helpful to know if you actually need 5.1 and 5.3, or are just curious. We have to limit the amount of CI to a reasonable subset versions, unless there’s a good reason for sticking to a particular version.

The check service is under [quite a lot of scraper load](https://www.tunbury.org/2026/07/27/week-30-2025/#:~:text=starting%20point.%20check.mint.caelum.ci.dev-,check.ci.ocaml.org,-outage), contributing to the outages as well. It’s holding up now thanks to Mark’s efforts, but if it gets worse then we’ll have to find some sort of authentication solution to dodge the slopobot army.
