Hi Peter,
Peter Müller:
Hello Michael, hello nusenu, hello Martin (???),
sorry for my late reply.
Yes, this change is due to an override of mine, committed as f3901759ede298e49cf5c056d0655b97e86cd211, affecting all location databases generated after January 9th, 2022.
thanks for your thorough reply. For me the relevant part was that this is due to a manual override. Maybe something I'll try to understand further: how can I easily determine if some information is provided due to a manual override vs. the raw WHOIS information? And if it was a manual override: What information did trigger that manual override?
I don't have any information on where these prefixes are actually located.
btw: I'm surprised that you read individual provider company websites to determine and manually override the location of individual ASNs or prefixes of a fiven AS, I didn't expect that to be feasible :)
kind regards, nusenu
