Sui Back Online After ‘Network Stall’ Leads to Six Hours of Downtime

The Sui Layer 1 blockchain has successfully resumed full operations following a significant six-hour period of downtime caused by a ‘network stall.’ The outage, which began early this morning UTC, halted transaction processing and required extensive coordination among the decentralized network validators and the core development team, Mysten Labs.

According to official communications, the network stall was attributed to an unexpected combination of factors leading to a consensus failure and subsequent node desynchronization. While the exact trigger is under internal review, preliminary reports suggest that a high volume of transactions coupled with specific network conditions overloaded the consensus mechanism.

During the six-hour disruption, the development team worked closely with validators via dedicated communication channels to isolate the issue. The resolution involved implementing a coordinated restart and configuration patch, allowing validators to re-synchronize their nodes and restore block production.

Sui confirmed via its official social media channels that the network is now processing transactions normally, and user funds were never at risk. However, the incident underscores the challenges inherent in scaling high-throughput blockchains and is expected to lead to a detailed post-mortem analysis focusing on improving network resilience against similar stalling events in the future.
