At some point SourceMod's GeoIP extension should probably be updated to use GeoLite2.

We have decided to discontinue our GeoLite Legacy databases effective January 2, 2019. We will stop updating the databases before that date (see “General Information” below), and the databases will no longer be available for download on January 2, 2019.
