Base, the Ethereum Layer 2 blockchain operated by Coinbase, experienced a significant outage lasting more than two hours due to an "Unsafe Head Stall" error that prevented block generation. The network has since restored functionality and resumed normal operations.
The technical failure temporarily disrupted transaction processing on the blockchain, which has become a major hub for decentralized applications and trading activity. Base processes billions of dollars in daily transaction volume and serves as a critical infrastructure layer for the broader Coinbase ecosystem.
The incident highlights the ongoing challenges faced by Layer 2 networks in maintaining uninterrupted service availability despite their role as scalability solutions. Coinbase has not disclosed detailed technical analysis of the root cause or whether additional safeguards will be implemented to prevent similar disruptions.
