Those look like they could be Akamai clusters on big providers networks. How big are the local Akamai clusters? How old? Smaller and older clusters don't support all content especially video streaming. We had to go to 10G before we got a cluster that supported video streaming, and its only about 3 years old at most. Even then there is content that is only supported by Akamai operated clusters like at the MICE exchange. I'm not exactly sure where MLB.com fits, when I go there most of it comes from our local cluster. But, I'm not going to subscribe just the verify that the live game content comes from the local cluster too, sorry. Also, its possible that your local clusters are topped out or disabled for some reason, Akamai is good about shedding load when a cluster is overloaded. The two clusters you talk about both seem to be located in Chicago, so there are probably reasonable clusters to serve you. Akamai is pretty good about that usually, and if there is a problem they usually find and fix it fairly quickly. If your question is why aren't you being served from the local cluster, I would ask when they were last upgraded, and see if they need to be upgraded, Akamai is usually happy to do so.

Sure, I'm seeing it from: 63.236.253.24 63.236.253.50 63.236.253.58 63.236.253.83 90.84.52.87 90.84.52.103 90.84.52.148 but it should be coming from 66.43.208.64/26 or 167.142.232.128/26.

Would anyone know, off-chance, if Akamai normally streams mlb.com content from all their CDN locations? Our upstream provider's (AS5056) Akamai cluster does not serve it up today, and we've had a few comaplints in the last month. Netflow monitoring shows that the content is being streamed from address space SWIPed to Akamai, but it's not coming from our upstream provider. We've replicated this in our own testing.
be easier to help if you told us what IP address you are seeing the traffic from cause then Akamai might be able to help you with which location it is streaming through.
