Try using nameservers on a different /24 and see if the problem goes

That's a good point. We've worked with Akamai in the past. Their CDN
solution works via DNS resolution. If your DNS servers are in Kansas,
you'll get the Akamai servers close to Kansas - whether you're there or
not. Akamai uses a combination of GeoIP and network operator contributed
IP ranges. For example, if you have an Akamai cache on your network, you
specifically tell Akamai what IP ranges should be served from that cache
- it doesn't seem to matter if these IP addresses belong to you or not.
I'm not sure how they deal with overlap.
