Looks good, but waiting on ipfs/kubo#10677 CI to be green before merging.

[gsergey418alt]

For the CI to pass, it needs this PR as a dependency. It won't build without the ReproviderStats structure containing the right values. You would have to merge this one first.

[gsergey418alt]

I could update the go.mod file of the kubo PR to point to the right branch on my fork, but you'd have to undo it before merging.

[gsergey418alt]

Just did that, you can approve the workflows.

Yes, I did it in ipfs/kubo@439f2d4

[guillaumemichel]

@gsergey418alt I updated the logic, let me know if it works for you

[gsergey418alt]

@guillaumemichel Yeah, it's probably a better idea to compute NextRun when displaying the stats.
