The Ethereum Pectra upgrade was activated on the Holesky testnet but ultimately failed to confirm, and developers are investigating

ChainCatcher news, according to CoinDesk, the Ethereum Pectra upgrade was activated at 5:55 on the Holesky testnet, but according to blockchain data, it was initially not finalized. Finalization refers to the state where once a transaction is confirmed and added to a block, it becomes immutable and irreversible. It is currently unclear why the testnet failed to finalize. Ethereum developers are investigating.

This is not the first time an upgrade has not been completed on a testnet; previously, in January 2024, when developers were testing the Dencun upgrade, the hard fork was initially not completed on the Goerli testnet.
