I maintain my own build farm and tried comparing my results against the official CI server:
$ guix challenge --substitute-urls="https://ci.guix.info"
14,224 store items were analyzed:
- 4,972 (35.0%) were identical
- 265 (1.9%) differed
- 8,987 (63.2%) were inconclusive
Of the 5237 build artifacts that were available on the substitute server, only 265 (5%) differed.
All of these items can be (and have been) built entirely from source, starting with Guix' initial "binary seeds", on (probably) different hardware and kernel compared to the CI system.
