noc@ got this email from Maxmind:
Dear MaxMind Customer, There was a recent attempt to update your GeoIP Legacy Region Database database using the automated GeoIP Update program from the IP address 2620:0:861:1:208:80:154:32 located in United States. The update failed because the term covered by your most recent invoice for this product has ended. To renew the invoice, contact sales@maxmind.com. Alternatively, to switch to online purchasing through your account portal, contact support@maxmind.com. If you have any questions, please contact us at support@maxmind.com. Sincerely, The Team at MaxMind
2620:0:861:1:208:80:154:32 is install1003, eqiad Squid proxy.
The full list of hosts querying Maxmind through the proxies can be looked up in the Squid access list.
install1003:/var/log/squid$ grep -i maxmind access.log | grep -o "client.ip[^,]*," (thanks @Volans for the query)
But if I remember correctly it's mostly used by Traffic, Analytics and Service Ops.
Opening this task as procurement as it seems contract/invoice related.
