Ethereum Foundation initiates Holešky network shutdown after completing Fusaka upgrade

The Ethereum Foundation has started the process of decommissioning the Holešky testnet, which was launched in 2023 primarily for large-scale validator and upgrade testing. Node shutdowns will commence two weeks after the finalization of the recent Fusaka upgrade. Holešky was instrumental in testing major upgrades like Dencun, Pectra, and Fusaka, the latter of which introduced PeerDAS to lower validator bandwidth needs and benefit Layer-2 networks. With its purpose fulfilled, Holešky will cease receiving client and infrastructure support. Operators are directed to migrate their testing activities to Hoodi and Sepolia, which are now Ethereum's main testnets for staking and development, signaling a shift toward shorter-lived, milestone-specific testnets.
