Sui Foundation Reports on Recent Network Outages Due to Software Bugs

The Sui Foundation has released an analysis of three recent network outages on its mainnet, attributing them to two separate bugs introduced in the v1.72 software upgrade. According to ChainCatcher, the first outage lasted approximately six and a half hours, while the second and third occurred on Friday morning and afternoon, respectively. The initial two disruptions were caused by a flaw in the 'address balance' feature, which led to negative balances and validation node crashes when transactions were canceled due to insufficient funds. The foundation acknowledged that an emergency fix deployed on Thursday carried known risks of further outages, which materialized on Friday morning. The third outage was triggered by an undisclosed random state bug during the restart of validation nodes to install a patch. Sui assured that user funds were never at risk and stated that both bugs have been fixed. Additionally, a mechanism to forcibly terminate stalled epochs has been implemented. The foundation noted that AI agents with access to their production systems significantly expedited the diagnostic process.
