Sui Network Experiences Second Outage This Year, Mainnet Stalls
On May 28, 2026, the Sui network, a layer 1 blockchain developed by Mysten Labs, suffered a network outage as its mainnet stalled, temporarily halting transaction processing. The project announced on X that the Sui Core team was actively working on a solution, but the cause of the disruption had not been disclosed at press time. This marks the second outage for Sui this year, following previous periods of degraded performance. Sui, launched in 2023, competes with Ethereum and Solana by offering high-speed transactions and low fees. The native SUI token dropped 8% in the last 24 hours amid mixed market conditions. Blockchain outages are closely monitored by traders and developers, especially for networks positioning themselves as high-performance infrastructure for DeFi and gaming. The team promised further updates as the investigation continues.
