HI,
Our GigaPOP (Front Range GigaPOP) and our own Akamai cache server's traffic
jumped significantly today. The theory (no data) is the Apple updates
released today.

The simple updates for a single machine today range in the 700mb-1.5gb or more range 10.7.2+iTunes+one iOS image. With a variety of devices it could easily be 4gb+ per user. Many broadband users are seeing slow akamai speeds because of these updates. I've seen 2+ hour download times myself....

On top of all that add that there are many apps that have also been
updated today to be in sync with new iOS features.

Subject: Apple updates - Affect on networkWith all of Apple's updates today (MacOS, iOS, Apps, etc) we saw a big
increase on one of our links to our ISP at 1pm Eastern.Did anyone else notice significant traffic jumps on their networks?

Yesterday, around 1PM ET, we saw a nearly 40% increase in inbound
traffic, almost all from Akamai. It continued until around 2AM this
morning, though, at one point, the traffic switched providers.
Interestingly enough, we are peered directly with Akamai at Equnix-
Ashburn, and at no point did this traffic use that link.
Last time we saw such discrete large inbound flows was the World Cup.
Would love to see some bandwidth graphs. 
Matt.

Here's one from another network.

Guess it was a good idea to upgrade that Akamai cluster's uplink to
10GE, even though 2*GE (or was it 4*GE) looked sufficient at the time.
Remember folks, "overprovisioning" is a misnomer, it should be called
"provisioning for robustness and growth".
If I may change the thrust a bit, this is of interest to me.
Just because we're in the midst of similar - changing from 2xGE to 10GE and
increasing the number of Akamai nodes.
Anyone have similar stats on that sort of conversion, and what to expect?
From what I can tell, there's a fair bit of local, off-net traffic coming to
ours, so I'm curious what the turn-up may look like.
This may be just idle curiosity, but what the hey.
It sounds like you have what Akamai calls an "AANP" deployment. In general, that should not serve users outside your network. There are reasons it can, and you should talk to Akamai about it if you think it is.
If you have questions about an on-net node, feel free to email Akamai's Network Support group, NetSupport@akamai.com. They are only M-F, but they can answer any questions you have.
