The base, the atherium layer -2 blockchain of the coinbase experienced a 33 -minute network outage on August. 5 Stop the block product after a defective sequencer infection.
Summary
- Block production of the base stopped due to a wrongly sequencer for 33 minutes on August 5.
- The outage was manually resolved, running with the infrastructure upgrade now.
- Other recent outages include hyperlicids and tones, which show scalability scaling risk.
In the conductor, an OP (OP) stack component that oversees the high-availability sequential cluster of the base was the root cause of the incident. For a postmortem issued by the base team, the sequencer handoff mechanism chose a backup node that the Vasan made a fully provision, which led to the ban in transaction processing.
Sequencer Handoff fails on-chain condition
The disintegration began at 6:07 pm when the primary sequence lagged behind the spike in the on-chain activity. The conductor, designed to maintain the sequencer, was chosen a new node mid-poison.
By reducing complete conductor functionality, replacement cannot invent another handoff, which is unable to the chain product blocks. At 6:12 am, Base formally announced the incident and started mitigation steps.
By 6:40 am, the team manually moved the leadership to a healthy sequeror and resumed block production. There was no fund list during the incident. Protocols such as Aave (AVE) and Moonwell avoided the seclusion errors for thanks to the Chanlink (Link) Sequences Optime Feed Circuit Breakers.
The team stopped the conductor, manually coordinated a Saif infection, and evaluated recurrence risks. Outage, which applied flashblock, withdrawals and deposits, total 33 minutes in total.
Basic structure fixes in progress
The base plans plan to upgrade your infrastructure that all the sequencecore added to the cluster may experience handoffs to prevent the recurrent. Additional testing and monitoring promotion will also be rolled out in the coming days.
The outage is the first major downtime based since September 2023, when the network was down for 43 minutes shortly after its public launch. The phenomenon has renewed the investigation of centralized sequential architecture, now more than $ 4.1 billion in total value.
The base is recently included in the growing list of L2 disruption, including Hyperlicid July 29 API Outage, which is caused by a traffic spike, and 40 minutes of ton of ton due to a 40 -minute stop of ton on 1 June.
