Base experienced a block interruption of 33 minutes due to a misconfiguration of the backup sequencer.

According to reports from Hash World, on Tuesday, the Ethereum Layer 2 blockchain Base experienced a fault due to switching to a poorly configured backup sequencer, resulting in a 33-minute block interruption. The incident occurred at 14:07 Beijing time on August 6, when the active sequencer delayed block production. The management sequencer's reliable system, Conductor, switched to another sequencer but selected the 'not ready mainnet sequencer' that was still being set up, leading to the inability to produce blocks. Subsequently, the Base Build account posted an explanation of the fault. Base founder Jesse Pollak stated that the core team responded quickly, and the network fully recovered by 14:40. The team also took time to ensure that there was no need for a chain reorganization. This incident exposed Base's reliance on centralized sequencers when handling large-scale transactions, presenting a single point of failure risk. The Base team stated they would update the infrastructure to ensure that all sequencers in the cluster can build blocks when selected.
