user7905: 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.

user252: 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
