@jerry Can you please remove the dualstack.t.sni.global.fastly.net CNAME from the media.infosec.exchange zonefile? I'm trying to see some media over here.
@nicholasburns Fastly's preferred model (as is the case with most CDNs) is to use a cname for non-apex domains (e.g., infosec.exchange). It's been like that for several years, but I did just move to the IP addresses a minute ago to see if that fixes the problem - what were you seeing?
