Base network released a detailed postmortem revealing that its August 5 outage lasted 33 minutes, not the initially reported 19 minutes, caused by a failed sequencer handover in the network’s high-availability cluster.
The Coinbase-backed Ethereum Layer 2 blockchain experienced a block production halt from 6:07 UTC to 6:40 UTC when an automated system called Conductor failed to transfer control between sequencer instances properly.
Automated Failover System Backfires During High Activity Period
The incident began when the active sequencer fell behind due to on-chain activity, triggering Conductor’s automated handoff to a backup sequencer.
However, the new sequencer was still being provisioned and couldn’t produce blocks, while Conductor wasn’t fully enabled on the replacement system to initiate another handoff.
Base’s monitoring systems detected the issue at 6:09 UTC, leading to a formal incident declaration by 6:12 UTC.
The team manually paused Conductor and transferred leadership to a healthy sequencer, taking several minutes to ensure no blockchain reorganization occurred during the recovery process.
The outage impacted deposits, withdrawals, block production, and Flashblocks functionality during Base’s unprecedented growth period.
The network recently overtook Solana in daily token launches, reaching 54,000 new tokens on July 27, driven by creator coin integration through Zora and Farcaster platforms.
Simple Breakdown: When the Traffic Controller Failed
Think of Base network like a busy highway system where sequencers are traffic controllers managing the flow of transactions.
Source: MirrorTo prevent problems, Base operates multiple traffic controllers in a backup system managed by a supervisor called Conductor.
When the main traffic controller started falling behind due to heavy traffic, Conductor automatically tried to switch to a backup controller.
However, the backup controller wasn’t ready for duty yet and couldn’t manage traffic properly.
Typically, if a backup controller can’t handle the job, Conductor would quickly switch to another one.
But in this case, Conductor itself wasn’t properly installed on the backup system, so it couldn’t make another switch automatically.
This left Base’s highway without a functioning traffic controller for 33 minutes, preventing all transactions from processing.
The technical team had to manually step in, pause the automatic system, and carefully switch control to a working traffic controller.
The manual process took extra time because engineers needed to ensure switching controllers wouldn’t cause any transactions to be lost or duplicated.
Once they confirmed everything was safe, they successfully restored normal operations.
Infrastructure Challenges Plague Growing Blockchain Networks
Base’s outage joins a pattern of infrastructure failures across major blockchain networks as they scale to accommodate mainstream adoption.
Recent incidents included Sui’s hour-long crash, TON’s six-hour disruption during DOGS token demand, and Solana’s repeated five-hour outages throughout 2024.
It can be said that the traffic controller failed due to a large volume of traffic, coinciding with Base’s explosive growth in creator economy applications, where social posts automatically generate tradable tokens.
Daily token launches surged from 6,649 on July 1 to approximately 50,000 by month-end, with 1.6 million tokens created and nearly 3 million traders participating.

In fact, with the network’s Flashblocks upgrade, block times have been reduced from 2 seconds to 200 milliseconds, processing international transactions under $0.01.
This has allowed Base’s creator economy to generate substantial trading volume through automatic token minting from social content. The network has expanded from 6,649 daily token launches to 50,000 within a month.
The ZORA token, for instance, achieved $200 million market cap while notable creator coins reached valuations exceeding $485 million.
However, security challenges accompanied this rapid growth, including the $2.5 million Arcadia Finance hack on July 15 through smart contract vulnerabilities.
As a result, Coinbase responded with a $5 million bug bounty program targeting Base network components.
Looking forward, Base has renounced its dedication to infrastructure improvements, ensuring sequencers can consistently perform well even during peak hours.
The network will release updates to enhance testing and deploy fixes to strengthen automated system robustness and prevent similar handover failures.
