The Sui blockchain’s status page reported a major outage on Thursday. The high-throughput blockchain has not produced a block for nearly two hours, according to block explorer SuiScan, with the team confirming on X that the network is experiencing a "network stall."

"The Sui Core team is actively working on a solution. Transactions may be paused at this time," Sui said on X.

According to the blockchain’s status page, “the issue has been identified and a fix is being implemented” as of 07:36 PDT.

This appears to be the third notable outage for Sui, including incidents in November 2024 and January 2026. User funds are likely unaffected.

Sui is a Layer 1 network developed primarily by Mysten Labs, a team spun out of Meta's canceled Diem stablecoin and wallet project.
