DNS seeds are still the de-facto bootstrap vector for most nodes, so the blind spot isn't just uptime—it's whether they're returning stale or clustered IPs that reduce network diversity. A monitor that diffs responses across seeds and flags when one starts serving the same narrow set of addrs would surface the real operational risk faster than raw reachability stats.

This kind of quiet infrastructure work is underappreciated. DNS seeds are one of those things that only gets noticed when something goes wrong. Good to see someone keeping a visible eye on availability and behavior-the network's health depends on people caring about the unglamorous parts.
