The Sui blockchain experienced its third major outage in under 48 hours on May 29, 2026, triggering a wave of liquidations among leveraged traders. According to data from CoinGlass, $1.88 million in SUI positions were wiped out, with long positions accounting for $1.72 million of that total. The disruption pushed SUI’s price down to $0.9035 on Binance, extending a decline that began with the initial outage on May 28. The token broke below the critical $1.00 support level, losing roughly 16% over the past week.
The third outage occurred during an epoch transition at approximately 4:30 PM EDT. While validators remained operational and generated system transactions, all user transactions came to a halt. The Sui team later identified the cause as a latent bug in how a specific failure state is preserved across validator restarts, which prevented the network from completing the epoch change. A fix was deployed, and service resumed shortly after.
The chain of disruptions began on May 28 when a crash bug in the gas charging logic, introduced in version 1.72 of Sui’s software, halted the mainnet for nearly six hours. No new checkpoints were recorded during that window. After over two-thirds of validators upgraded to a patched version, the network came back online on May 29 at around 8:32 PM UTC. However, a second outage followed hours later, traced to a variation of the same underlying issue. Reports suggest the root cause ties back to changes made to enable zero-fee stablecoin transfers.
This marks Sui’s third significant disruption in 2026 alone, following a six-hour consensus divergence event in January and a congestion-related outage in November 2024. The Sui Core Team has promised a detailed incident review. No user funds were lost during these incidents.
