GFW has some different settings that they use, similar to "ThreatCon"... if
civil unrest is happening, its working is changed. During party
conventions, they change it too.
So when a foreign visits China, that experience might be different from one
visiting during a different time period.

Also, some hotels that only accept international guests backhaul traffic
thru Hong Kong, providing an experience that looks much closer to US/Europe
broadband.
