Thanks for reaching out to us!

It's indeed on our list to evaluate other geolocation databases and
possibly switch over. I'll bring this topic up at tomorrow's metrics
team meeting to discuss possible next steps for such an evaluation. I'll
get back to you here to share the results.

One question, though, that just came to mind: Are there archives
available for past IP2Location LITE databases, or do you provide just
the latest version? Having archives, possibly even back to 2002, would
be pretty useful for Tor Metrics. (I didn't look around as much on your
homepage, so please apologize if this question is already answered there.)
