Ethereum bungles "Holesky" testnet launch

Ethereum prepared to launch a new test network, called "Holesky", which was supposed to be massive compared to the mainnet in order to work on scaling problems. The launch was supposed to coincide with Ethereum's September 2022 "Merge", in which the network finally pulled off the long-awaited switch from proof of work to proof of stake.

However, the Holesky launch was a failure when developers misconfigured the network, causing it to fail to initiate. Developers announced they would try to relaunch the project a week after its intended go-live date. At least it was just a testnet.
