SUI Slides 7% After Nearly Six-Hour Sui Mainnet Outage

SUI came under pressure after the Sui blockchain suffered a sudden mainnet interruption that halted transactions for nearly six hours, rekindling concerns about network reliability following prior outages. Sui's core team said the chain was experiencing a "network stall" and warned users that transactions could be paused while engineers worked on a fix. The disruption began after the rollout of Sui Core version 1.72, where a bug in gas-charging logic triggered a complete stop in transaction processing. The network was down for about five hours and 55 minutes before coming back online. After the restart, validators continued to operate below normal performance levels, leaving conditions degraded even as basic functionality returned. SUI fell roughly 6.6% during the outage to around $0.90 as traders priced in downtime risk. Following the restart, the token pared some losses and traded near $0.93, though sentiment remained cautious while the market waited for clearer signs of stability. The pullback follows a strong run earlier in the month, when SUI gained about 50% and climbed to $1.41 on ecosystem momentum, including growing institutional participation and staking activity tied to a Nasdaq-listed firm. The latest outage adds to a record of disruptions: Sui was also offline for more than six hours in January 2026, and in November 2024 validators reportedly entered a crash loop for several hours. Despite recurring incidents, Sui remains a notable DeFi venue, ranking among the top chains by total value locked with more than $542 million across protocols. The project continues rolling out features such as zero-fee stablecoin transfers and privacy tools. The team said it will publish a full post-mortem on the failure and measures to prevent a repeat.
