Sui Network Resumes After Six-Hour Outage

Sui Network experienced a six-hour outage on January 13, 2026, impacting key functions, confirmed by the Sui Foundation and core team efforts via Twitter.

The incident underscores vulnerabilities in Layer-1 blockchain systems, affecting over $1 billion in on-chain value, with SUI token experiencing notable price fluctuations post-resolution.

The Sui Network experienced a major six-hour outage, disrupting numerous decentralized applications (dApps) and transactions. Sui Foundation, Leadership, Sui Foundation, stated, “Sui Mainnet is currently experiencing a network stall, and the Sui Core team is actively working on a solution. Be aware that dApps such as Slush or SuiScan may not be available, and transactions may be slow or temporarily unable to process at this time.” The interruption, which froze over $1 billion in on-chain value, was identified and resolved within the same day.

The Sui Foundation and Core Team addressed the network stall quickly. Through coordinated efforts, network functionality was fully restored, advising users to refresh apps or browsers for better performance post-outage.

The sudden stoppage in the network affected user confidence as essential dApps like Slush and SuiScan faced accessibility issues. This led to a slowdown in transaction processing, impacting user interactions and network utility.

The financial repercussions included a brief spike in the SUI token price following the outage confirmation, swiftly followed by a notable decline. This fluctuation highlighted the vulnerability of crypto assets to operational disruptions.

The Sui Network incident report cited validator consensus issues as the cause, similarly identified in the previous November 2024 outage. Identifying and rectifying such vulnerabilities remains crucial for maintaining network stability in high-throughput environments.

The incident could prompt wider discussions on the resilience of Layer 1 networks in handling high transaction volumes. Insights from previous disruptions can drive technological enhancements, safeguarding future reliability and user trust.
