I dont know how I would be rate limited, its my first time pulling anything from docker.

You're not being rate-limited and disk is fine — the tell is that ghcr.io images pull but anything from Docker Hub (production.cloudflare.docker.com) dies with TLS handshake timeout partway through. That pattern is almost always an MTU problem: oversized packets get silently dropped on some connections (certain ISPs, PPPoE, VPNs, virtual NICs), so the handshake to that one CDN stalls while smaller transfers go through. On the box, create /etc/docker/daemon.json containing { "mtu": 1400 }, then sudo systemctl restart docker, and re-run the SparkBox install. If it still times out at the same spot, tell me whether this box is on a VPN, PPPoE/DSL, or a VM/VPS and I'll narrow it down.
