The complete history of Ethereum incidents
Every serious moment in more than a decade of mainnet — the DAO, the 2016 spam war, Black Thursday, the 2020 chain split, the Merge, the May 2023 finality delays — and why not one of them stopped the chain.
Reference
Everything behind the counter.
The front page makes one claim — Ethereum has never gone down — and checks it live. These articles are the long version: every incident with sources, how the record compares to other chains, and the mechanisms that make an unbroken record possible in the first place.
Ethereum vs Solana uptime, compared
Solana has halted around seven times and needed coordinated restarts to come back. Ethereum has never halted and never needed one. The full side-by-side, with what each outage actually was.
The May 2023 finality delays, explained
Twice in two days the beacon chain stopped finalising for roughly 25 and 64 minutes — while still producing blocks the whole time. What finality is, what broke, and why it was the closest call so far.
Why Ethereum upgrades cause zero downtime
The Merge changed the consensus mechanism of a live network securing hundreds of billions, with no maintenance window. How hard forks ship on a running chain without an off switch.
Client diversity: nine clients, no single point of failure
Ethereum isn’t one program. Independent teams write independent clients in different languages, and that redundancy is the reason a bug in one of them is an inconvenience, not an outage.
