We don't confirm or attest individual host-key fingerprints for ssh.railway.com, so we can't verify whether that specific fingerprint is one of ours. The endpoint is served by multiple hosts, each with its own key. Those hosts change routinely and without notice, so the fingerprint you see can differ between connections and change over time.

We don't publish a fingerprint list, a known_hosts entry, an SSHFP record, or a host CA for this endpoint, so there is no official verification reference we can point you to.
