Base chain resumes block production after one hour outage

Base, Coinbase’s Ethereum Layer 2 network, experienced a temporary halt in block production on mainnet, resulting in an outage of roughly 30–45 minutes before service was restored. According to the Base status page and subsequent reporting, block production stalled when the network’s sequencing infrastructure encountered a fault, leaving new transactions unable to be processed during the incident. Once engineers mitigated the issue and switched back to a healthy sequencer configuration, Base resumed normal block production and transaction processing. The incident highlights the central role of the sequencer in optimistic rollup-style Layer 2 chains like Base, where a single or small set of sequencers are responsible for ordering transactions and posting data to Ethereum. In this case, a problem in the failover process and/or sequencer configuration caused the chain to stop finalizing new blocks, but there is no indication that user funds were at risk, as the fault affected availability rather than the integrity of assets or the underlying Ethereum security model. The outage has renewed scrutiny of operational robustness and redundancy in L2 infrastructures, as even short periods of downtime can disrupt DeFi activity, trading, and application reliability on networks built atop these systems.
