Bug: Anonymized EDNS Client Subnet showing wrong location

Hi Team,

I live 100km from Sydney (so close in Australian terms). With Anonymized EDNS Client Subnet turned on it's directing some of my traffic to Melbourne POP's (another city, different state). Turning it off resolves it and sends me locally to Sydney.  You can see me toggling here - making a difference of 8ms to 20ms.

Is this because my anonymised EDNS record is likely showing the incorrect location? Is there a way to update this? 

Thanks
