I figured I’d wait a few days and try again the first few times I encountered this, but it’s persisted for more than two weeks now.Could these be related to the fact that dnsvis.net is trying to reach these servers via IPv6 and I think they use Hurricane for transit. Since HE and Cogent is a major gap, this causes them to time out trying to reach the C root server over IPv6.
It could well be… I haven’t tried to research the hosting of the dnsviz.net <http://dnsviz.net/> web server I’m connecting to and I don’t know anything about how their backend is structured (whether it’s on the same server or somewhere else, for example). However, c.root-servers.net <http://c.root-servers.net/> is not the problem being reported. The servers that provide the zone in question are (reportedly): arpa. 84508 IN NS a.ns.arpa. arpa. 84508 IN NS b.ns.arpa. arpa. 84508 IN NS c.ns.arpa. arpa. 84508 IN NS d.ns.arpa. arpa. 84508 IN NS e.ns.arpa. arpa. 84508 IN NS f.ns.arpa. arpa. 84508 IN NS g.ns.arpa. arpa. 84508 IN NS h.ns.arpa. arpa. 84508 IN NS i.ns.arpa. arpa. 84508 IN NS k.ns.arpa. arpa. 84508 IN NS l.ns.arpa. arpa. 84508 IN NS m.ns.arpa. c.ns.arpa does share an IPv6 address with c.root-servers.net <http://c.root-servers.net/>, however, so yes, the Cogent peering issue could be part of it. Seems irresponsible to me that a root-server (or other critical DNS provider) would engage in a peering war to the exclusion of workable DNS. Owen
