The outage was caused by the same network update software bug that disrupted the protocol on Thursday, which resulted in nearly six hours of downtime. The Sui layer-1 blockchain experienced another disruption on Friday, causing a “network stall” that temporarily halted block production, before normal activity resumed, according to the Sui team. Network activity “may be paused,” the Sui team said. The network disruption lasted for over three hours and 30 minutes at the time of publication, according to the Sui network’s uptime dashboard. Sui's mainnet validators experienced disruptions on both Thursday and Friday. Sui The last block before the disruption was produced at about 11:51 UTC on Friday, according to the Suiscan block explorer. Network activity on the Sui mainnet resumed at about 3:30 UTC. The Sui team said in an update: The interim fix had a “low probability” of causing a network disruption, and the long-term software fix has now been implemented by a majority of Sui validators. The incident follows several major disruptions and network outages, including Thursday's outage, which caused a nearly six-hour outage due to a “crash bug in the gas charging logic,” according to the team. The crash was the second major network disruption in 2026. In January, the network went offline for over six hours, halting block production due to a consensus bug. Validators submitted conflicting transactions to the protocol’s checkpoint mechanism, and the network was unable to reach the necessary threshold for consensus, according to the post-mortem report.
