<div dir="ltr">Akamai is a caching network. DNS does not provide the sort of intelligence necessary to direct requests to the most appropriate server, so you will always just hit the server closest to you. If that server happens to have the content already cached then it will serve it up itself. If it doesn't have some or all of the content required (cache miss) the server will act as a proxy and fetch the content from the closest upstream server on the akamai network that does have the content, and then hold onto it for an amount of time as defined by their internal algorithms in case anyone else needs that content.<div><br></div><div>*this is a simplified explanation of what is a complex system*</div><div><br></div><div>Thanks</div><div>--Damian</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jun 16, 2017 at 2:29 PM, Tim Raphael <span dir="ltr"><<a href="mailto:raphael.timothy@gmail.com" target="_blank">raphael.timothy@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Mark,<br>

You’ll find that Akamai’s algorithms will retrieve the content from the origin and keep it at varying stages of “warm” in their caches based on demand.<br>

I’d be pretty unimpressed if I was a US / EU journo trying to get Australian news from a webpage 500+ms RT away.<br>
