[AusNOG] Anyone else notice the click frenzy traffic

[Chris Jones]

Because most CDNs use DNS-based GSLB  - via a CNAME record - and you can't have a CNAME for the Apex (root) of the domain.

Not to say the redirect isn't on a CDN, necessarily - just that it needs to have a standard A record.

Some providers are working around this now if the CDN hosts the DNS infrastructure as well (eg Amazon and Route-53/CloudFront/ELB integration)
