Sui mainnet experiences three outages; upgrade vulnerabilities are the main culprit.

DeepFlowTech
Deep Tide TechFlow News, June 1st, according to The Block, the Sui Foundation released an incident report on May 31st, revealing that its mainnet experienced three consecutive outages from May 29th to 30th, all caused by two separate vulnerabilities introduced in the v1.72 version upgrade. The first two outages were caused by a gas fee calculation error triggered by the new "address balance" feature, where funds were still deducted after transaction cancellations, leading to negative account balances and crashing validator nodes; the third outage was caused by a potential vulnerability in the random number generator triggered during node restarts, resulting in the network epoch being unable to close properly. The Sui Foundation stated that all known issues have now been fixed, user funds were unaffected throughout, and settled transactions were not rolled back. They also plan to further optimize fault tolerance mechanisms to ensure that similar vulnerabilities in the future will only affect individual transactions rather than causing network-wide downtime.
