Hi J,
As Patrick mentioned, on-net private Akamai clusters should not be serving out of your network unless you desire them to or there is a configuration mistake.
There is a small caveat; we direct users by which DNS they use and not by end user IP address. So if a user has switched ISPs and not updated their DNS, they could still be directed to the previous ISP's on-net cluster. Of course, this would be viewed as serving offnet but usually makes up a very small % of traffic (think <1%)
Unfortunately, Akamai has no control over this aspect but ISPs have a few options to mitigate it.
If you can let me know more info about what you are seeing, we would be happy to investigate & help further.

Andrew, Actually, I've already been talking to you somewhat about our upgrades in the area, I believe. I'm mostly curious about what the user impact is on the cluster and link upgrades in terms of experience when that happens. This seems to be a common progression, so I'm curious ahead of time.

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.
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.
