I have yet to see a geo-ip address for my IP that shows me even on the correct side of the country. I wouldn't trust this information as far as you can throw it ... and I've had this IP address for nearly 6 years now.
I don't see any way to report it though.
I forgot to add the link in my original comment. But as you mentioned we are showing VPN as true, that indicates a very interesting situation. Can you ping our support, please?
If you can also mention that, you came from HN, that will be fantastic. We will open an engineering ticket first thing Monday and look closely into this. The situation is unusual, and I am sorry about the inconvenience.
