The Sui Foundation has released a post-mortem report detailing the causes behind the three mainnet outages that occurred on May 28 and 29. The report indicates that the initial two network halts were a direct result of a gas-charging bug that was introduced as part of the v1.72 "address balances" upgrade. The third and final outage was attributed to a different issue, a randomness-state fault that was exposed when a separate patch, known to carry risks, was implemented.
