Steady. No change on record for ul.ac.za in the last day; this reading matches the one before it. The steady record is signed like every other reading. Watch it to catch the next move the moment it lands.

Signed at scan time. Check the math yourself. Every line above is part of one signed observation. Re-hash it and check the Ed25519 signature in your own browser; the only network request the check makes is for the published public keys.
