Sui’s blockchain network experienced its second significant disruption of 2026 this Thursday, remaining offline for nearly six hours following a critical bug discovered in a recent software upgrade. The native SUI token experienced an immediate decline, dropping substantially before mounting a partial recovery.

The incident originated from the network’s version 1.72 deployment. A critical flaw within the gas charging mechanism triggered a mainnet failure, completely suspending transaction processing capabilities. Via their official X account, the Sui development team acknowledged the problem, explaining that operations had ceased “due to a halt caused by a crash bug in the gas charging logic introduced by the 1.72 release.”

Sui Mainnet is currently experiencing a network stall. The Sui Core team is actively working on a solution.

Initially, the network issued alerts about a “network stall,” cautioning users that transaction capabilities might be temporarily suspended while engineers worked on a resolution. The complete restoration process required almost six hours — precisely 5 hours and 55 minutes — before the mainnet resumed normal operations. Following the restart, validator nodes continued experiencing diminished performance levels.

SUI Token’s Market Response

Market participants reacted swiftly to the news. According to CoinGecko tracking data, SUI tumbled approximately 6.6%, bottoming out at $0.90 during the network disruption. By early Friday morning, the cryptocurrency had staged a modest comeback, trading around the $0.93 level.

This decline occurred just weeks following an impressive rally for the digital asset. During early May, SUI had climbed roughly 50% to reach $1.41, fueled by multiple favorable catalysts, including a Nasdaq-listed corporation staking a substantial portion of the token supply.

The development team had previously unveiled forthcoming capabilities, including fee-free stablecoin transactions and confidential transfer functionality. Mysten Labs co-founder Adeniyi Abiodun, whose company develops the Sui protocol, confirmed these roadmap items during his Consensus 2026 presentation.

Recurring Network Disruptions

This Thursday’s disruption wasn’t an anomaly. During January 2026, the Sui infrastructure similarly went dark for over six hours. Prior to that episode, in November 2024, validator nodes became trapped in a continuous crash cycle lasting approximately two and a half hours.

This represents the third documented major interruption to the Sui blockchain infrastructure within the previous twenty-four months.

Current State of the SUI Ecosystem

Notwithstanding these technical setbacks, Sui maintains its position as a significant blockchain platform. DeFiLlama data shows it ranking 13th by total value locked, safeguarding approximately $542 million distributed across 137 decentralized protocols.

Sui’s mainnet debuted in May 2023, emphasizing rapid throughput and scalability designed for institutional financial applications. The development team committed to publishing a comprehensive incident analysis and post-mortem documentation within the upcoming days.

Validator performance metrics continued displaying suboptimal readings shortly following the network’s restoration to active status.
