Hi relay operators,
as you might have heard, MaxMind has changed access and use of their GeoLite2 databases:

This affects Onionoo and tor, and I'm trying to find a working alternative on the following ticket:
https://trac.torproject.org/projects/tor/ticket/32978
Today I think I found a possible alternative by using data from another provider. But before I name it here, I'd first want to find out how accurate it is.
I tried resolving relay IP addresses of relays that have been running in the past week and compared that to our existing lookups using MaxMind's October database.
The result is that 7669 relays (93%) had the same country code and ASN.
I put the remaining 7% on the following wiki page:
https://trac.torproject.org/projects/tor/wiki/doc/MetricsGeoipComparison
I'd like to hear from you which data source is right and which is wrong (or if both are wrong).
If you'd like to help, please leave comments on the ticket or in the "Comment" column on that wiki page by February 19, 2020.
Thanks for helping!
Hello again,
I'm bumping this thread, because there's (finally) news on finding an alternative to MaxMind:
https://gitlab.torproject.org/tpo/metrics/trac/-/issues/32978
(Yes, you'll have to scroll down quite a bit to find the news, it's a long ticket.)
Can relay operators please take a look at that ticket and see if they find their relay in the table with different country results?
It would be neat to identify patterns there and possibly improve the accuracy of the new database.
Thanks for your help!
I run 3 relays with Scaleway, one in Paris and 2 in Amsterdam, the new alternative places them all in France.
whois correctly describes the range as being in Amsterdam:
