why is my IP geolocation tool suddenly failing?

man, i'm completely stuck here and honestly kinda desperate. i launched 'what is my country?' a few weeks back, it's a simple web tool that shows your current country and ip location, and it was working perfectly fine. we're talking weeks of solid, accurate ip geolocation data, no problems at all. it relies heavily on those ip lookup services, ya know?

but for the last 24 hours or so, it's just... broken. it's showing completely wrong country data for a ton of users, or sometimes just failing to resolve their location altogether, especially for people in europe and parts of asia. i've been pulling my hair out trying to figure it out. i checked all the api logs, confirmed my api keys are definitely valid, even tried switching to a different, backup ip geolocation provider just to rule that out, but the problem just keeps happenning. it's like something fundamental broke with how ip lookup works or something. has anyone else dealt with something like this with their ip geolocation services? what are the common pitfalls or any advanced debugging steps i might be totally missing here? this is super critical for my app's main feature and i'm losing my mind trying to fix it
