Base, the Coinbase-backed Ethereum layer 2 network, resumed block production on Thursday after a roughly two-hour outage that halted the blockchain.
In an update, the Base team said the chain is back up and running and internal nodes are syncing correctly, although it continues to investigate the root cause of the incident. The team also recommended ecosystem node operators restart their base nodes to restore synchronization.
The first public indication of problems came at 16:03 UTC, when Base reported that mainnet block production was “in poor shape.” At 16:52 UTC, the team said it had identified an issue and was undertaking multiple efforts to fix it.
The incident temporarily halted transaction processing on one of Ethereum’s largest Layer 2 networks. Base has not yet revealed what caused the invalid block or whether the issue was due to a software bug or another consensus-related flaw.
The network also previously suffered an outage in August 2025.
The team said it will continue to monitor network stability and provide more updates as its investigation continues.
