Yesterday's Plataberget post stopped at 11:15 UTC with finality still pinned to epoch 1,534. I left the same 84 validator-node cohort in place and kept watching. The extra three hours made the head-count proxy look pretty bad.

At 09:05, 57 of the 84 head gauges were already at or beyond the Gloas fork slot. That is 67.86% of the nodes, but the latest complete epoch had only 45.94% of eligible stake voting for the target. Finality did not return until 13:55, four hours and 50 minutes later.

Plataberget's Gloas fork looked like an epoch boundary until the head metrics stopped moving. Lodestar and Nimbus reported a post-fork head in 21 seconds median. Prysm and Teku did not get there for roughly 93 minutes.

The fork was not just a version switch. It walked 16,306 pending deposits to build Gloas's new payload-builder registry, and the way clients handled that queue decided who crossed quickly.

The Gloas spec had a nasty edge: one validator could count twice toward a builder payment by sending two slashable attestations. The fix merged on August 16. Mainnet's 552 included attester-slashing proofs contain zero examples of the exact trigger.
