And then there’s bandwidth
Notes:
US1-3 were conducted sequentially at a single location in Everett, WA. Signal strength appeared to be good for all carriers.
The US based Akamai server appears to be in Cambridge, MA
US1-3 was conducted during the afternoon of Saturday 7 Aug.
AP1 conducted on an ad hoc basis in Hong Kong. The Akamai server was apparently located in Dingxi, China
