  • The Sui blockchain suffered multiple significant outages in May 2026, including a nearly six-hour halt on May 29 due to a bug in the 1.72 software update. These disruptions caused sharp declines in the SUI token price, with a 6.6% drop immediately after one outage and a total 20% weekly decline during consecutive network failures, severely impacting investor confidence and market stability.[Pluang][Decrypt][Cryptonews.net][CoinLaw]
  • Technical issues on the Sui mainnet in late May 2026 included repeated outages and halts lasting between one to six hours, with block production stopping at times and network stalls occurring multiple times. These events disrupted transactions and user activity, raising ongoing reliability concerns amid the blockchain’s third major disruption in 2026.[UseTheBitcoin][Bitcoin News][CoinLaw][Pluang]
  • Following the outages, the Sui network successfully restored operations, demonstrating responsive issue management by developers. However, the consecutive halts tied to software bugs highlight persistent challenges in maintaining network stability and reliability, with investigations ongoing to address root causes and prevent further incidents.[Pluang][Bitcoin News][CoinLaw]
  • The SUI token was trading at approximately $0.92 after the six-hour outage on May 29, 2026, with a scheduled token unlock set to occur within two days. This upcoming unlock is a significant event that could influence token supply dynamics and market behavior amid the broader token value decline due to network instability.[Reddit r/Sui]
