For those following along at home, it appears that Akamai was the culprit. Didn't even know they offered geolocation services! Many thanks and much respect to those who reached out off-list.
Best,
Tim

Subject: Re: Auth0 geolocation?Apple and Best Buy are other ones that just came up over the weekend, seems to be spread out across an entire /17. Oddly, we've had this /17 for close to a year and a half, and this is just popping up...

Subject: Auth0 geolocation?Anyone know who Auth0 is using for geolocation services? Have a customer reporting that Auth0, Lowes, Bank of America, and some other sites are reporting their IP in the wrong location. Checked the usual suspects, BrothersWISP.com geolocation providers list, etcetera and they’re all showing in the correct location.
Thanks,Tim
