Sui Network Offline for Six Hours as Crash Bug Triggers 6.6% Token Drop

• Sui mainnet experiences second six-hour outage in 2026 after gas logic bug, sending token down 6.6%
• Sui remains among top 15 blockchains by TVL, but ongoing performance issues persist after service restoration

On May 29, 2026, Cointelegraph reported that Sui Network’s mainnet went offline for nearly six hours following a critical bug in the gas charging logic introduced with the 1.72 update. The disruption froze all network transactions, affecting users and developers, and marked the second major Sui outage of the year. Even after core services resumed, multiple validators continued to report degraded performance, raising concerns about the network’s ongoing reliability.

SUI, Sui’s native token, dropped by 6.6% after news of the outage spread. Once the network was restored, the token partially rebounded, trading near $0.93, but stability remained a concern as technical issues persisted among validators.

The scale and frequency of recent outages prompted renewed scrutiny of Sui’s status as a leading Layer 1 blockchain. Sui ranks among the top 15 blockchains by total value locked, hosting $542 million across 137 protocols. The incident has sparked debate among observers and infrastructure users regarding the protocol’s long-term dependability.

Sui Network developers acknowledged the incident and said a full post-mortem would be published in the coming days. As of this report, no further details have been provided about the root cause or ongoing resolution.

As of May 29, 2026, 18:08 UTC, SUI is trading at $0.912, down 2.93% over the past 24 hours, according to the latest market data.
