Where does one get the basic .*-config.json, .*-topology.json and .*-genesis.json files for package building nowadays? The URLs that always worked for me seem down, e.g.:

https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/mainnet-config.json

This makes it quite hard to rebuild this package that depends on the configs. Somewhere on the interwebs they mention a switch from hydra.iohk.io to cache.iog.io, but nope, that doesn’t work either. (Or perhaps the URL structure is completely different.)

I could probably just reuse the files from 1.35.3 for 1.35.4, but (sort of) dislike the idea; I like to keep things clean & correct & buildable long-term.

So what’s the issue here? Is it just temporary downtime? Has there been a change in the config file provisioning? Or have the config files themselves been replaced? (If so, is there a migration guide?) Looking at the 1.35.4 release notes, I can’t spot any news concerning the .json files.

The hydra.iohk.io site went through unexpected retirement (and may not be restored). But the release notes for 1.35.4 already have updated links for binary download (which points to update-cardano-mainnet.iohk.io) and configs (which points to https://book.world.dev.cardano.org/environments.html).

Also, the config files you download from that site are available on github here

    Well, the cardano-world repo doesn’t have tags, but I assume that the 1.35.4-node-bump branch might do. 🤪 In retrospect, the reason why my vigorous GitHub searches found nothing was … the renaming of mainnet-config.json to config.json. That’s a level of encryption that my brain just could not penetrate.
