Hi Brion, such issues may be based on routing, depending of the peerings between the Hilton ISP and Wikimedia. One would need to check both ASes and use the respective looking glasses (does Wikimedia have one?) to check the routes. Many routes are also assymmetrical, so up- and downlink can vary.*nod*

This remembers me similar problems we have had remarked in Hong-Kong (I don't remember the ticket number) where people had (still have?) problems to upload data to Commons even with theoretically good-enough connections.
At that time is was IMO pretty obvious that we suffer of a lack of End-2-End approach of the problem (in particular lack of tool to make the correct measurements).
