Sui said its mainnet resumed operations around 4:30 a.m. on May 29 after a network pause caused by a gas fee logic crash bug introduced in version 1.72. According to the project, the disruption kept the blockchain offline for 5 hours and 55 minutes. Sui also said a full incident review would be published in the coming days, underscoring how software updates to core blockchain infrastructure can temporarily halt transaction processing when fee-handling logic fails.
