Would you care to share the IPs? (both for the Hetzner PTP one and the local ISP stratum 1)

Is the 2.33s stable? If so, after deducing the stable offset, it could still be valuable.

`/dev/ptp0` and `/dev/pps0` magically showed up and yeah, it appears to be stable. Chrony actually has it marked as a non-false ticker atm and is marked as a backup. Here's the stats:

I don't feel great about sharing the discovered stratum 1's on the open internet, but my email address is in my profile.
