Sui’s Layer 1 blockchain experienced further disruptions on Friday, causing a “network shutdown” that temporarily halted block production before normal operations resumed, according to Sui’s team.
Network activity “may be interrupted,” Sui’s team says he said. According to Sui’s network uptime, at the time of publication, the network disruption lasted for more than three hours and 30 minutes panel.

According to The Guardian, the last block before the disruption was produced on Friday at around 11:51 UTC Suiscan block explorer. Network activity on the Sui mainnet resumed around 3:30 UTC. Team Sui said in an update:
“Both today’s and yesterday’s stops are due to the interaction of version 1.72, which introduced address balances and gas charging logic. The fix deployed yesterday was an interim measure to restore network functionality.”
The momentary fix had a “low probability” of causing network disruption, and a long-term software fix has now been deployed by most Sui validators.

The incident followed several major network disruptions and outages, including Thursday’s, which caused an almost six-hour outage due to a “failure in gas charging logic.” According to to the team. The outage was the second major network failure in 2026.

The Sui network went down in January due to a consensus error
In January, the network went offline for over six hours, halting block production due to a consensus error. According to the postmortem, validators submitted conflicting transactions to the protocol’s checkpoint mechanism and the network was unable to reach the threshold necessary to achieve consensus. report.

Sui’s team said the January disruptions were not caused by network congestion, user funds were “never at risk” and no “certified transactions” were reversed. he said then.
“The issue was detected and resolved by Sui’s checkpoint certification and quarantine mechanisms, which prevented a user-visible fork at the expense of halting progress,” according to the autopsy.
High-throughput sharp contract blockchain networks consist of several layers, including data availability, transaction execution, and validator consensus, which introduces more potential points of failure.
However, network failures in crypto also affect centralized service providers, including exchanges, which have fewer coordination challenges than decentralized blockchain networks.
In May, cryptocurrency exchange Coinbase experienced a momentary service outage due to an Amazon Web Services (AWS) outage, forcing it to switch to “auction” mode before full service was restored.
