Or with my local Unbound

That's a mighty impressive response time. Any input on how I can make it that good? I resolve to root DNS zones, not ISP DNS/public DNS.

@bortzmeyer Three of the four old servers have been down for months; I've been nagging the folks in charge of the ntp.org domain to get it updated and we recently got the in-zone NS-set updated to include PCH and Dyn. The delegation was updated today, but as you saw it looks like the one working server of the old four had a hiccup. :-(
