The iOS5 effect (network)

[Garp]

Thought some of you might get a kick out of this.

This is what iOS5 looks like from an ISPs perspective:

Thankfully for ISPs (and Apple sysadmins), Apple uses Akamai, a Content Delivery Network. They have servers all over the world within most major ISPs infrastructures, so when you go to get iOS5 from Apple, you're actually getting it from an server run by Akamai fairly near to your ISP, rather than pulling from some central location.
That graph is showing the traffic in one medium sized US ISP for their connection to the Akamai servers they host, so that's only the traffic for one ISP :shocked:

I can't see anything :(

I even quoted & C&P the link, but nothing loads.

Hmm.. Wonder if that's an IPv6 problem. Can you see this?

I can see both...and that's quite a spike :eek:

[Kitten]

Can see them both now.

Paul, OK if I post that image elsewhere? Will re-host it, just making sure it wasn't private or anything :)

[Garp]

Sure, feel free. It's posted on a public mailing list for network operators somewhere :)

I think this might be a problem with our new web-nanny thing, it's not allowing loads of pics through. Grrrr!

Ahh whoops.. I.. urm.. re-organised my site/blog quite significantly and forgot to make sure the picture was in the new location. I'll fix that :D
