Are NS records more important than A records?
So I was helping a friend set up a site using a2hosting with a domain at easydns.com. He changed the A records at easydns to the IP listed for his hosting at a2hosting, but after a 36 hours there was no change. We went to change the NS at easydns initially but a pop-up showed a dire warning about doing so. Anyway, after the 36 hours we changed the NS records to match the ones at a2hosting, and voila, the site loaded and the built-in SSL cert process could finish.
This surprised me as I thought the main record for a website to load was the A records, generally. Why were the NS's the crucial bit here? Thanks.
