Members mirror pool for Linux images

Access
Membership. Downloads require a mirror access token issued to pool members.
New memberships are currently paused while we finish the node-2 rollout — the
catalog above stays visible so members can check availability and checksums.
Upstream project mirrors remain the right place for general public downloads.
Peering & sync
Upstream. Images are pulled nightly over rsync from tier-1 project mirrors
and verified against the published checksum files before being promoted to the
pool. Node de1 carries the Ubuntu line; node de2 carries the Debian, Alpine and
Rocky sets. Operators running their own mirror who want a peering slot can reach
us at the address listed in whois.
