Where Does Cloudflare Think I Am? (opens in new tab)

It claims London E1W for my IPv4 and IPv6 RIPE PI space, and the same location/postcode for my EE home broadband. Generic 'London data centre' postcode? Or the location of the nearest Cloudflare POP, maybe? (Whois on the PI blocks shows a correct postcode some distance from London FWIW.)

[Edit: same location and postcode for a Vodafone UK v4 address too.]

1000km off though checking here it has the right ISP https://radar.cloudflare.com/ip

Other ip locations have the correct location.

Correct country (in the EU) but off by hundreds of kilometers. I find it rarely to be correct whenever I get a "new login from..." mail from Google or others.

Ir gets my zip code right but doesn't geolocate it properly. My zip code is a 0.2 sq miles.

Shows the town my ISP is in. Which seems like an odd approach.

2.33 km off for me. Pretty cool

Off by 300 kms for me

was off by 15 miles / 24 kms for me
