Why is my SaaS tool's geolocation API constantly thinking users are in the middle of the ocean?

Alright, AdsVolt fam, I'm back with another installment of 'My Geo-Location API is Drunk: The Saga Continues'. Last time, it was just a bit tipsy, placing users a few hundred miles off. Now? It's gone full-blown blackout, completely lost at sea.

My SaaS tool's geolocation API, which relies heavily on accurate IP address lookup, has gone from mildly confused to full-blown existential crisis. We're no longer talking about placing someone in the wrong state; it's literally putting users in the middle of the Pacific Ocean, or worse, Antarctica! I'm trying to figure out if my API key is secretly a treasure map to Atlantis or if there's a more mundane, fixable bug at play.

Here's a sample of the kind of bizarre output I'm getting from the API logs. Notice the utterly unhelpful coordinates and the massive accuracy radius:

{
  "ip": "198.51.100.1",
  "country": "Unknown",
  "city": "Deep Ocean",
  "latitude": -34.0000,
  "longitude": -56.0000,
  "accuracy_radius": 1000000,
  "time_zone": "Etc/GMT+2"
}

Has anyone experienced such extreme inaccuracies with their IP geolocation services? Are there common configuration pitfalls that lead to this kind of 'lost at sea' data, or specific debugging steps I should be taking to identify why my API thinks everyone's a deep-sea explorer? Help a brother out please...
