The Sui Foundation announced on Wednesday that the network is now “fully operational,” confirming that transaction flow has returned to normal. Users experiencing lingering issues were advised to refresh their apps or browser windows.
The outage was first acknowledged at 3:24 pm UTC, when the foundation informed its 1.1 million followers on X that Sui core developers were actively investigating the issue. According to the foundation, the problem was initially detected at 2:52 pm UTC and fully resolved by 8:44 pm UTC, resulting in approximately 5 hours and 52 minutes of downtime.
While the foundation confirmed the disruption was caused by a “consensus outage,” it has yet to provide details on the root cause.
Second Major Network Failure Since Launch
Wednesday’s disruption marks Sui’s second major outage since the blockchain launched in May 2023. The network previously experienced a significant failure in November 2024, raising fresh concerns around reliability despite Sui’s reputation as a high-speed blockchain.
Other layer-1 networks, including Solana, have faced similar challenges in the past. However, Solana has avoided major outages for over 18 months after implementing emergency coordination tools and rolling out critical validator updates.
SUI Token Sees Brief Price Reaction
Despite the extended outage, Sui’s native token showed limited market reaction. The SUI token briefly jumped about 4% following confirmation that the network was back online before retracing to trade near $1.84.
Meanwhile, the Sui Foundation rolled out a blockchain-based framework to create a verifiable AI economy, combining on-chain data, accountable AI systems, and autonomous commerce.
