I am experiencing something very similar but it seems to be centered around Google. When I go to google.com it sends me to google.com.mx which is the Mexican version in Spanish. Although I speak some Spanish, this is a pain. This is happening across all devices and computers, both PC and Apple (iPads, iPhones). We have a satellite internet connection, Exede5 through Viasat but that does not seem to be a known problem and this is a fairly new situation that never happened before.
I can't seem to figure out what is happening. I have even tried to contact google to correct the IP signifier but have not received any responses in two weeks and it keeps on happening on all devices. Does anyone have any idea how to solve this problem? I know I can enter google.com/ncr and it will force it to go to regular google but this is not a fix to the problem. Thanks for the help.
