X-Vercel-IP-Country header returning wrong country

[vilihei]

I am using X-Vercel-IP-Country to identify if certain content on the website should be shown to user or not. After trying it from different key regions I noticed that it returns GB when accessing the website from Philippines. When using other IP based location services I get correct location, but Vercel for some reason thinks the address is in Great Britain.

I have the same issue. In my case, the user is located in Canada, but the Vercel returns me San Francisco, USA (sfo1)

I tried from Argentina and it is showing US, happened also with Colombia.
