When good recursives go bad: why does 22.214.171.124 not give the same answer as 126.96.36.199?
Anyone got a suggestion for this? Why would Cloudflare DNS be unable to resolve the SOA record of a given domain if Google DNS can? 188.8.131.52 can also resolve this without trouble. Its not a one-of either, it repeatedly refuses to answer, but does for other domains. Hmmm. Is this a disconnect between Cloudflare and .ca root? A caching issue in Cloudflare? Hmm. If we “$ dig @d.root-servers.net -t SOA 100years.ca” and then check each of the roots (c.ca-servers.ca etc), they all work from my house… Hmm.
