TL;DR - MaxMind sent us an email, and they're changing how their license keys work for pulling database updates, and they've flagged our account as one that's still using an older version of the updater program itself, which is not compatible with these changes. We need to look into this and update our updaters across our infrastructure before 2019-08-15. There's some refs to this in SRE's puppet repo in modules/geoip, I'm not sure if there's also other updaters being run for e.g. Analytics using the same keys that aren't driven by that puppetization.
Soon after August 15, 2019, we will be hashing license keys to enhance the security of MaxMind accounts. However, because you are using an older version of our GeoIP Update program, we are unable to provide this security feature for you. We recommend upgrading your GeoIP Update to our latest release and generating a new license key by following the steps below.
Upgrade your GeoIP Update.
Generate a new license key to use with GeoIP Update.
Make sure to copy down your new license key as it will not be available in full after the initial creation.
If you lose your license key, you can generate a new one on that same page. The newly generated license key will be shown to you in full only once for you to copy it down for safe keeping.
