Post-Mortem Report: Ethereum Mainnet Finality (05/11/2023)

Ethereum's mainnet network suffered lack of block production leading to a temporary delay in epoch finalization. Two incidents caused approximately 200 blocks to be missed, with a lack of finality, resulting in inactivity penalties and an estimated loss of revenue for block producers. Validator slashing also occurred due to operator errors during a client switch. High gas prices caused resource exhaustion for some clients. The incidents caused significant drops in network participation and required temporary stops in finalizing epochs.
