Review Comment:
I didn't manage to check if this tracks, but my AI reviewer wrote:
> ubuntu-cpp-bundled-offline sets ARROW_OFFLINE=ON. In
ci/scripts/cpp_build.sh, this clears /etc/resolv.conf before compilation. With
*sccache added, Crossbow supplies SCCACHE_BUCKET and CMake selects remote
sccache instead of local ccache.
>
> On its first compiler invocation, sccache verifies the S3 backend. With
networking disabled, server startup fails and compilation exits rather than
falling back. I reproduced this using sccache 0.12.0 against an unreachable S3
endpoint.
