Avoiding Location Errors in Segment Events with Mixpanel

we send out events through Segment, and a lot of times that ends up with users' locations getting set to Boardman OR (which is where the Segment servers are located). I'm guessing this is a fallback behavior in Mixpanel when it doesn't have location data in the event payload, it looks at where the request itself came from. Does anyone know a quick way to avoid this behavior, every few months I have to explain to someone on my team that no, we don't have some kind of super-user hub in Boardman OR, it's just a data error
