Wasn't so much users are traffic. We had Los Angeles, Montreal, Helsinki, Sydney, Buenos Aires, and Montreal data centers with GeoDNS routing. Each relay synced with the others to have consistent data. While also syncing with about 10 of the other top relays to replicate their data. The current LMDB for strfry is 152GB (will be backing up and pruning soon). Was planning to have a separate "archive" relay for historical data (now on-hold).
