Its not just the hosting servers.
Your connection to AGN will be as fast as the slowest component in the connection chain. and there are MANY between you and AGN's servers
In my case, there;s at least 5 net work devices (and at least 3 security gizmos) to even get off campus (writing this at work, over coffee....). After that its off to Seattle, and I dont know after that, as it can vary depending on a number of factors.
AGN servers likley see at least that many before net traffic even gets out to the wild. Better servers wil help but wont solve all of it
