Sui Network Faces Back-to-Back Outages Amid Validator Bug

The Sui blockchain is currently navigating a period of significant technical turbulence following two major network stalls in quick succession. After resolving a nearly six-hour outage caused by a critical software bug, the network experienced a secondary disruption just hours later, raising concerns about the stability of its recent infrastructure updates.

Technical Failure and Coordinated Recovery

The initial disruption on May 28 was traced back to a "crash bug in the gas charging logic" introduced in the network's 1.72 software release. This glitch effectively halted mainnet settlement for 5 hours and 55 minutes, requiring a coordinated effort from the validator community to resolve. To restore consensus, engineers rolled out a fix that necessitated more than two-thirds of the total network stake to perform a manual upgrade, highlighting the complexities involved in maintaining decentralized uptime during a critical failure.

Infrastructure Disparity and Future Scrutiny

Interestingly, while the network's validator services suffered a major outage, public RPC (Remote Procedure Call) nodes maintained 100% uptime throughout the ordeal. This distinction meant that while users and decentralized applications could still access network endpoints, no actual transactions could be settled until consensus was restored. The recurrence of a stall shortly after the initial fix has placed renewed scrutiny on Sui’s software rollout procedures and the reliability of its recovery protocols, with a full incident report expected in the coming days.
