So has anyone else seen a HUGE spike in wireless traffic with the IOS7 update? Our wireless had a dramatic shift at exactly 11:55AM CDT that’s still going strong.

Yes there was a noticeable increase which corresponded with the release of iOS7.

Our wireless traffic jumped up to 5 times what it was before the update. On Wed, 18 Sep 2013, Eric T. Barnett wrote: > Date: Wed, 18 Sep 2013 13:29:55 -0500 > From: Eric T.

We are. Typical load at this time on a Wednesday is around 1.5Gbps aggregate for our ~22K-ish concurrent users. It’s currently cooking along at 2.8Gbps with a very clear jump right around that time.

Not seeing any spikes yet on our wireless infrastructure, but I am sure it is just a matter of time though once classes are done for the day.

On a side note, the #1 app sorted by bytes in our Palo Alto firewall over the past hour is "itunes-base."  I thought it would be categorized as something else like "apple-update" or "apple-appstore."  Anyone else with a PAN seeing something similar?


Wireless bandwidth had doubled since noon today.

We actually have an Akamai cache on campus, which has taken the brunt of the load in the past. It doesn’t seem to be getting the traffic this time around, they are trouble-shooting it now.

Ours is not as bad, percentage wise, but is still quite significant:

Akamai can't decide which cache they want our clients using...they keep switching us back and forth.  It'd be awesome if they left it on our 10G link where we have extra capacity.

Ours didn't at first, but eventually kicked in and thankfully took on a good 2 gigs worth. Pete Morrissey
Here's our Akamai stack.  Using about all of that 1Gig uplink!!

Our Akamai boxes are doing the same thing, they seem to be taking the load off and on.

They tracked our problem down to an issue on their side -- they were not properly processing our BGP advertisements. They've fixed it but I haven't seen any change in traffic just yet... ----------------------------------- Robert G Colantuoni Senior Programmer Analyst CIT - Network and Classroom Services SUNY Buffalo rgc@buffalo.edu 716.645.3552 >

I saw a major jump (especially out of high schools which go out of the SDC link).  I put our new iBoss web filter's traffic shaping to the test by capping Akamai at 600 megabit at each commodity internet connection.  Seems to be keeping it under control pretty well!  :)

We peaked at just over 9.5Gbps today on our campus (30 second averages). Jason On 09/18/2013 01:29 PM, Eric T.

We haven't seen a spike as such, but that’s probably due to the time it was released since we are in Aus. Certainly our app id on the firewalls now shows itunes-base has the largest bandwidth user, it's gone from number 37 yesterday to number 1 since IOS7 release today .... 6.5 hours -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph    : +61 8 8313 4800
Anyone have more info or a contact for the Akamai edge cache server? I can't seem to find anything on their website about the program. Thanks Tim Cappalli, Network Engineer LTS | Brandeis University cappalli@brandeis.edu

We participate in both the Akamai Accelerated Networks Program (AANP) and another CDN (beta) that doesn't want to be mentioned publically.

 

During most of last semester, our caching subnet saw 100Mb/s IN and 400Mb/s OUT average. This was with an uplink that averages ~ 2.5Gb/s.

 

It was turn-key – it took me more time to push the approval through our legal dept than it did to get the servers online. They support both IPv4/6 and use eBGP to keep track of your address space so they can correctly route your customers to the local on-campus cache.

 

They restored caching last night at 8pm and we saw about 400Mb/s offload to the cache and our internet link flattened out.
