k, I read your proposal an have a question. I assume that your MAE-west cache will act as a parent for the MW ISP's (otherwise, there's no data in the cache). That means that all outbound traffic from MW is routed through your cache, isn't it? That also means that e.g. all transatlantic traffic will flow through your lines. Or am I missing something? For our AMS-IX exchange in Amsterdam I would think that the best thing we could do is to connect all ISP's top level caches as neighbours, without a special AMS-IX parent cache. All ISP's connected have their own transatlantic lines...
