I thought the parent is trying to say accessing content via Akamai will be slower when using Google Public DNS/OpenDNS because they don't support the purposed DNS extension thus the request is routed to a non-local server instead of local one?
(Akamai is my main reason of not using OpenDNS to this date, otherwise I would make a switch for long)
Ahh, this is possible. Not as likely in the US, but possible. We're working on it. At least it's fixed for Youtube, all Google properties, a bunch of other CDNs now.
But yeah, some big guys still remain! We'll get 'em.
Title isn't misleading, but your comment is.
