Sui Network back online after ‘crash bug’ causes 6 hour outage

The Sui mainnet has resumed after a bug in a network update took it offline for 5 hours and 55 minutes.

Sui Network is back online after a nearly six-hour outage on Thursday, which it attributed to a bug introduced by an update, marking the layer-1 blockchain’s second period of downtime in 2026.

Sui posted to X on Thursday that activity on its mainnet had resumed after “a halt due to a crash bug in the gas charging logic introduced by the 1.72 release. A full incident review will be shared in the coming days.”

Sui had earlier shared that the blockchain was “experiencing a network stall” and said that transactions could be paused until a fix is rolled out.
