Ask HN: Did the Spain/Portugal blackout disrupt .es DNS root servers resolution?

3•ljahier•3h ago

The .es ccTLD relies on four Red.es-operated authoritative servers (a.nic.es, c.nic.es, g.nic.es, h.nic.es) protected by UPS and standby generators. But the rest of the network equipment along the transport route is not redundant.

Has anyone seen DNS lookup errors, time-outs or elevated resolution times for .es domains since the outage? Any logs or measurements are available ?

Doesn't look like it: https://atlas.ripe.net/dnsmon/group/es.

Most likely these are anycast hosted in multiple locations. From the west coast of the US, I can get responses from c,g, and h in under 60 ms, which means I'm hitting a replica within North America. I get a response in about 165 ms consistently from a, so that may well be hosted exclusively in a single location.

Also,

    host -t TXT -c CH id.server X.nic.es

Indicates Calgary, Seattle, and "us" for c,g and h. a didn't seem to provide any useful information in the CHAOS records that I tried.
