The nameserver be like: "I know a guy that knows a guy that can help you."

From the look of the thumbnail, i tought Mike would say "Dunno" and the video would end.

Every time you're troubleshooting: "It's not possible for DNS to be the cause, it's completely unrelated." Also every time you're troubleshooting: "It was DNS."

03:52 Actually, it's 13 ip addresses. This is a hard limit related to the size of DNS packets. These 13 addresses used to belong to 13 servers, but this was long ago expanded by the use of anycast routing to share those ip addresses among multiple servers. A packet sent to one of those addresses get routed to a server in the closest location. These days there are over a thousand root name servers.
