Consecutive Sui mainnet outages traced to gas-charging bug; validators patch network as SUI plunges ~20%

Sui's mainnet was halted for a second consecutive day, with network activity paused while the team investigated the incident; the prior outage reportedly lasted nearly six hours ^{[1] [2]}.

The developer community attributed the disruptions to a software bug in the gas-charging logic introduced by a recent upgrade, and validators implemented what the project described as a long-term fix before transactions began flowing again ^{[1] [3]}.

The outages coincided with market stress: Sui’s token was among the worst-performing top-100 assets for the week, sliding about 20%, and the interruptions have been linked to millions of dollars in losses for users of Sui-based protocols; community posts noted this was the network’s third outage this year ^{[2] [1] [4]}.

Validators report the chain is processing transactions again after deploying the fix, while observers continue to flag stability concerns following consecutive halts ^{[3] [1]}.
