I occasionally have the same issue.
I live in the central US. Sometimes when I access the VPN (I alternate from Dal, Chi, SLC, Seatl, &others) then I go to a site like Yahoo (with many national derivative sites) and it thinks I am in India, Japan, or other countries. Or the advertisements are not in English. What is wrong with the VPN? Also I get surges in upload data when Im not doing anything. This does not happen when the VPN is off, only when it is on.
