Geo-targeting not working!

man, i'm pulling my hair out here. for the past few days, i've been trying to fine-tune our geo-targeting logic 'cause we had some reports of inaccurate regional content. i thought i was making progress, but now it feels like the location accuracy is actually worse than before. we're seeing IPs from the US showing up in, like, eastern europe, and users in canada getting served content meant for australia. it's completely messing up our regional content delivery and our analytics.

i'm running a simple IP lookup to test and this is what i'm getting in my logs. look at this:

[2024-07-26 14:35:12] INFO: IP: 172.217.160.0, Detected Country: Poland
[2024-07-26 14:35:13] INFO: IP: 203.0.113.45, Detected Country: Brazil
[2024-07-26 14:35:14] INFO: IP: 192.0.2.10, Detected Country: Germany
[2024-07-26 14:35:15] INFO: IP: 104.16.0.0, Detected Country: South Africa

these are all supposed to be US IPs from our test accounts! i've checked our IP database provider, cleared caches, even restarted the servers, but nothing. it's like our geolcation service just went completely haywire. i'm desperate for a fix before this impacts our conversion rates even more. anyone faced this before? what am i missing?
