Packet A leaves the UK enroute to Los Angeles to retrieve a .png file. Packet B leaves Ireland for the same .png file, but only has to hop down the street to the local AWS data center...stops by the pub on the way back for a pint and then still delivers the image faster than Packet A, duh!? For those about to crash a website simply because they can’t spell “C.D.N.” we dedicate this deeply informative episode on the subject. We cover inquiry from Josh about how to setup your test labs, how to learn squid and also the alternative benefits of a CDN.
