Disclaimer: I work in the CDN77 ops team and I wrote the frontend. We mainly use it internally to help us get stable pingable IPs for latency monitoring when we're troubleshooting a specific network/customer. Then we throw the IPs into SmokePing/Smoke2 (internal tool) and watch the latency from different upstreams. Our backend pings all IPv4s on the planet regularly. We think someone else might find it useful, so i thought i'd share.
