ISO uploads go straight at the forge host over the direct (grey-cloud) route, sharing that box's connection with everything else it serves, and ISO dispatches happen whenever needed rather than just on the monthly schedule. Add --limit-rate to the release-asset curl, set from a documented UPLOAD_BWLIMIT env (12M per upload, ~100 Mbit/s; worst case ~400 Mbit/s with all 4 runner slots uploading).

This only covers the ISO workflow. The nightly image pushes are skopeo with no rate knob, so those get paced with traffic shaping on the runner host instead.

ISO uploads land on webnx's inbound pipe, the same one Matrix lives
on, and a manual dispatch can push several multi-GB ISOs at once from
the runners on ghan. Give the release-asset curl a --limit-rate so a
batch of ISO jobs can't flatten the link by itself. 12M per upload
(about 100 Mbit/s) with up to 4 runner slots keeps the worst case
around 400 Mbit/s; tune UPLOAD_BWLIMIT once webnx's real inbound
capacity is measured.
