Under [Instance Configuration](https://gitlab.wikimedia.org/help/instance_configuration), Wikimedia GitLab currently reports the following SSH host key fingerprints:
| Algorithm | MD5 | SHA256 |
|---|---|---|
| ECDSA | 8a:29:0a:54:bb:b0:06:21:f6:1a:7e:f7:b0:d6:7d:dc | SHA256:i+fWYVTGTn8XXsbrYDOVUHCZZCk6rRyCG4rJk5nxxh8 |
| ED25519 | 70:d1:0d:b6:1d:bb:9d:d3:a1:12:10:f0:c3:3c:7f:c8 | SHA256:lKmdy0Xvi4AXeEWEbg3sM5Zc8GRSqqbhnP7uti8xKBs |
| RSA | f4:48:50:da:5e:cd:eb:5e:0f:a6:1b:77:c6:9b:34:cb | SHA256:u3BILUTd6NsM9/ItWulh3uzqcKh3SXzpkC+oNKmbG4k |
But when I connect to GitLab, SSH reports different host key fingerprints:
> The authenticity of host 'gitlab.wikimedia.org (2620:0:861:1:208:80:154:14)' can't be established.
> ECDSA key fingerprint is SHA256:V1Q7vVIt/XR2yuue3kUa27/+cSwrCm8wLDfBROh8HMs.
> ED25519 key fingerprint is SHA256:eGFVaGXuc0AkXE4n+SrBbp1Mkul4RAvZPWbVUrZ7sM0.
> RSA key fingerprint is SHA256:hwHUSYaoPvrQGmphy+sCLbfGqiTcSdJ41FmRKIF+wK0.
