This is a mirror of the GeoLite2 databases, which were put behind a "license key wall" on December 30, 2019.
There's a cron job to update it weekly.
I'm not a lawyer, but I skimmed the license below and I'm pretty sure I'm allowed to do this. I'm also pretty sure nobody cares if we do.
I guess you have to follow the license, which is basically CC-BY-SA but with extra words because California.

GeoLite2 End User License Agreement
Revised on December 20, 2019
By downloading or using our GeoLite2 Database, you are accepting and agreeing to the terms and conditions set forth in this GeoLite2 End User License Agreement (this "Agreement").
MaxMind, Inc. ("MaxMind"), a Delaware Corporation, offers a line of free databases that provide geographic information and other data associated with specific Internet protocol addresses (each a "GeoLite2 Database" and collectively the "GeoLite2 Databases"). The data available through the GeoLite2 Databases is referred to in this Agreement as the "GeoLite2 Data". The term “Services” as used in this Agreement means the Geolite2 Databases and the GeoLite2 Data available at GeoLite2 Free Downloadable Databases on the MaxMind website, www.maxmind.com (the "Website").
ADDITIONAL POLICIES, TERMS AND CONDITIONS.
The following policies are incorporated into this Agreement by reference and provide additional terms and conditions incorporated herein by this reference and/or related to the use of the Website:
Creative Commons Corporation Attribution-ShareAlike 4.0 International License (the “Creative Commons License”) MaxMind Data Processing Addendum (“DPA”) MaxMind Privacy Policy (“PP”) MaxMind Website Terms of Use (“WT”)
This Agreement controls in the event of any conflict with the above-referenced documents. Thereafter, for any conflicts among the above 4 documents, the priority and precedence of interpretation is DPA, PP, WT and Creative Commons License.
OTHER DATABASES AND PRODUCTS.
This Agreement does not apply to your use of any databases or products offered by MaxMind other than the Services. If you use other MaxMind databases or products, additional or other terms and conditions shall apply to your use of such databases and products, and you agree to pay all applicable charges.
LIMITED GRANT OF RIGHTS.
Subject to the terms and conditions of this Agreement, to the extent the Services contain any copyrightable elements those copyrightable elements are governed by the Creative Commons License. You must provide attribution of your use to MaxMind (an example of attribution: “This product includes GeoLite2 data created by MaxMind, available from https://www.maxmind.com“).
In addition and if you are using the Services for internal use, subject to the terms and conditions of this Agreement, MaxMind also hereby grants you a non-exclusive, non-transferable limited license to access and use the Services for your own internal business purposes.
With respect to either or both of the above licenses, (i) you agree to use the Services only in a manner that is consistent with applicable laws and (ii) you may not remove or obscure any copyright notice or other notice or terms of use contained in the Services.
NO USE OF GEOLITE2 DATA FOR FCRA PURPOSES.
The parties understand and agree that MaxMind is not a consumer reporting agency as defined by the Fair Credit Reporting Act, 15 U.S.C. §1681 et seq. ("FCRA"), and that the Services do not constitute "consumer reports" as defined in the FCRA. You agree that you will not use the Services to determine any consumer's eligibility for any product or service to be used by a consumer for personal, family, or household purposes. You also agree that you will not use the Services (i) as a factor in establishing a consumer's eligibility for credit, (ii) as a factor in establishing a consumer's eligibility for insurance, (iii) for employment purposes, (iv) in connection with a determination of an individual's eligibility for a license or other benefit granted by a governmental authority, or (v) in connection with any permissible purpose as defined by the FCRA.
ACCURACY EXPECTATION: NO USE OF GEOLITE2 DATA FOR IDENTIFYING SPECIFIC HOUSEHOLDS OR INDIVIDUALS.
Due to the nature of geolocation technology and other factors beyond its control, MaxMind cannot and does not guarantee the accuracy of the GeoLite2 Data. The GeoLite2 Databases contain only the geographic data available and the availability of such data is not consistent for all regions. Furthermore, none of the GeoLite2 Data reliably identifies any geographic level or division more precise than the zip code or postal code associated with an IP address. Accordingly, it is imperative that you and your end users not rely on the GeoLite2 Data to identify a specific household, individual, or street address. You acknowledge the foregoing limitation of the GeoLite2 Data and agree represent and warrant that you will not use or encourage others to use the GeoLite2 Data for the purpose of identifying or locating a specific household, individual, or street address.
ADDITIONAL RESTRICTIONS.
Disclosure of Services. Except as explicitly permitted by the Creative Commons License, you will not disclose the Services to any third party or after notifying MaxMind of the anticipated disclosure and obtaining MaxMind’s prior written consent to the disclosure. To the extent you disclose the Services to a third party as permitted by this Agreement, you will impose upon the third party the same or substantially similar contractual duties imposed on you and the rights provided to MaxMind as in this Agreement, including those in LIMITED GRANT OF RIGHTS, ADDITIONAL RESTRICTIONS, and DATA PROCESSING and, where not inconsistent with the other terms of this Agreement, as in the Creative Commons License. You are responsible for the acts or omissions of any third parties with which you share the Services. Security of the Services. You will maintain reasonable and appropriate technical and organizational measures for the protection of the security, confidentiality, and integrity of the Services (including protection against unauthorized or unlawful processing and against accidental or unlawful destruction, loss, or alteration or damage, unauthorized disclosure of, or access to, such data). In the event you discover a data incident involving the Services, you shall promptly notify MaxMind and fully cooperate with MaxMind, at your own expense, in remediating the incident. Destructions of GeoLite2 Database and GeoLite2 Data. From time to time, MaxMind will release an updated version of the GeoLite2 Databases, and you agree to promptly use the updated version of the GeoLite2 Databases. You shall cease use of and destroy (i) any old versions of the Services within thirty (30) days following the release of the updated GeoLite2 Databases; and (ii) all Services immediately upon termination of the license under this Agreement. Upon request, you shall provide MaxMind with written confirmation of such destruction. Provision of Data to MaxMind. The Services provided by MaxMind under this Agreement do not require MaxMind to process Personal Information on behalf of Licensee.
