I still need to finish testing, but here's my plan:
1. Test backup: create `keyservers/facts/backups.json`, update cronjob schedule to run right now, and make sure backup is created:
2. Test GeoIP update: create `keyservers/secrets/geoip_license.json`, and then run `cd keyserver && yarn update-geoip`
3. Test push notifs on both iOS and Android (see @palys-swm's instructions in a comment below)
4. Test URLs (make sure keyserver works)
