difference with caching when connected to telia internet

Regarding, caching services like Netflix OCA and Google GGC, does anyone know if there is something strange that occurs when connected to Telia BGP AS1299 ? .meaning, if I have local Netflix/google caches, and then later I establish a BGP session for Internet with Telia/BGP 1299, would there be something that would make netflix and google caches reachable via Telia look better than my local ones ?! -Aaron
