Why is my location tool's geolocation API so moody?

hey everyone,

we run 'What is My Location?', a pretty straightforward web tool that helps folks find their current coordinates and see it on a map. for the most part, it's been a reall workhorse, super solid. but lately, this thing has developed a serious personality disorder. like, it's having a mind of its own, and our IP geolocation seems to be taking a vacation without us.

• sometimes, it's incredibly accurate, it's like it knows where i'm sitting right now. scarry good.
• other times, though, it decides i'm chilling in, say, antarctica or some obscure village in tibet. we're talking continents away, not just a few blocks off. it's wild.
• this seems completely random, but we're starting to wonder if it's tied to specific browser versions or maybe some sneaky VPNs/proxies people use, even though we try to account for that stuff.

we've gone through our code with a fine-tooth comb, double-checked all our internal calls to the geolocation API, made sure permissions are being requested properly, and scoured for any obvious errors. honestly, nothing's screaming "fix me!" at us. it's like a ghost in the machine.

has anyone else seen such erratic behavior with their IP geolocation API implementations for location-based tools? seriously, any secret sauce or obscure settings we might be missing? anyone faced this before?
