Base Network Restores Functionality Following Two-Hour Block Production Halt
The Base network, an Ethereum layer-2 scaling solution incubated by Coinbase, has successfully returned to normal operations. This recovery follows a significant technical disruption that effectively froze the blockchain, preventing both transaction processing and the creation of new blocks for approximately 120 minutes.
Timeline of the Network Disruption
Technical difficulties first surfaced on Thursday at 16:03 UTC, at which point the official Base status channels flagged that mainnet block production was exhibiting “unhealthy” behavior. As the situation evolved, the development team worked to isolate the fault, eventually reporting by 16:52 UTC that they had pinpointed the source of the instability and were actively deploying corrective measures.
Root Cause and Remediation Efforts
According to the official post-incident briefing, the outage was triggered by the generation of an invalid block, which subsequently disrupted the network’s consensus mechanism. While the chain is now operational and internal nodes have successfully re-synced, the engineering team is still conducting a deep-dive forensic analysis to determine the exact catalyst-whether it was a latent software vulnerability or a deeper consensus-layer error.
To ensure full network health, the Base team has issued a directive for all ecosystem node operators to manually restart their nodes. This step is essential to guarantee that all participants are synchronized with the current state of the ledger.
A Pattern of Growing Pains for Layer-2 Infrastructure
This recent event is not the first time the network has faced downtime. It follows a similar, albeit shorter, incident in August 2025, where the chain experienced a 29-minute suspension of services. These recurring outages highlight the inherent complexities of maintaining high-throughput layer-2 networks, which must balance rapid transaction finality with the rigorous security requirements of the Ethereum mainnet.
As Base continues to scale, the team has committed to ongoing monitoring of network stability. Further technical disclosures are expected once the comprehensive investigation into the invalid block is concluded. For those tracking the evolution of Ethereum scaling solutions, this incident serves as a reminder of the challenges involved in managing decentralized infrastructure at scale.
For additional context on the network’s history, you can review the details of the previous August 2025 outage that marked the first major downtime for the platform.
