Sui Network Faces Outage, Transactions Halted for Three Hours

The Sui Network mainnet is currently experiencing a significant outage, lasting approximately three hours. The core team is actively working on a solution, but dApps like Slush and SuiScan are unavailable, with transactions being slow or halted.

  • Last valid transaction recorded at 2:22 p.m. UTC; checkpoint was 234608191.
  • An hour without checkpoints indicates the blockchain is effectively "stuck," halting new transactions until resolved.
  • Investigation started 30 minutes post-outage; fix identified after 1.5 hours.
