The Ethereum Foundation and core developers have decided to launch a "shadow fork" of the Holesky testnet to address network failures that may occur during Pectra upgrade testing and avoid upgrade delays. Holesky experienced a severe interruption during the Pectra test on February 24th and is expected to resume by the end of March, resulting in some research and optimization work being postponed. This malfunction is not related to Pectra itself, but rather caused by a critical client software configuration issue. In the end, the community reached a basic consensus to maintain the shadow fork in the short term to advance Pectra testing, while Holesky may continue to serve as a testing network for future Fusaka upgrades.
