Cname
The trouble with CNAMEs
When you query DNS for something you ask your local DNS recursive resolver for all answers it has about a hostname of a certain type. If you’re going to a website your browser asks your resolver for all records for “google.com” of type “A”1or “AAAA”, but that’s not important right now and it will either return all the A records for google.com it has cached, or it will do the complex process of looking up the results from the authoritative servers, cache them for as long as the TTL field for the reply says it should, then return them to you.

“What would you do for 25% more sales?”
It’s panicked gift-buying season, and I got mail this morning from Boutique Academia, part of their final push before Christmas.
They’re hoping for some Christmas sales in the next three days. They do make some lovely jewelry – ask Laura about her necklace some time – so I clicked on their mail.
That’s not good. I like Boutique Academia, and fixing email and dns problems is What We Do, so I took a look.
Safari isn’t quite as bad with not-exactly-truthful error messages as Internet Explorer, but I still don’t really trust it. Perhaps the problem is with the click-tracking domain in the email, rather than with boutiqueacademia.com? So I open the base page at http://boutiqueacademia.com, get redirected immediately to https://www.boutiqueacademia.com – which fails to load.
OK, start with the basics. DNS.
