Just realised, Yahoo's probably buying intl transit from Vocus, so this makes sense...
Correct. Vocus are the first international provider to peer at APE and advertise all their non-NZ customer prefixes I believe. This sort of thing is common in other parts of the world. AT&T do it (I think? At WIX, anyway), but only for a couple of special customers or something. So, if you are of the opinion that "APE = domestic", it's probably a good idea to re-think that. If you have transparent proxying with source address spoofing on your international links now would be a good time to either stop doing source address spoofing, or put your domestic links through the switches that do the transparent proxying. Alternatively, a quick hack that might work for some people until you can do something properly is to stop Vocus accepting your prefixes over APE, and do not accept prefixes from them over APE either. -- Nathan Ward
