Sui Foundation on Sunday published its review of the outages that knocked its blockchain offline three times across Thursday and Friday, attributing the disruptions to two distinct bugs introduced with its v1.72 software release.
The account confirms a third halt and answers a question left open in The Block's earlier coverage about whether the incidents shared a root cause.
According to the foundation's timeline, the first halt began around 10 a.m. ET Thursday and ran until roughly 4:30 p.m., somewhat longer than the 5 hours and 55 minutes The Block reported from the status page at the time. A second outage hit early Friday and was resolved by late morning, and a third began around 4:30 p.m. ET Friday and lasted until about 10:20 p.m.
The first two halts stemmed from the same flaw in how Sui charges transactions for gas, exposed by the "address balances" feature that v1.72 introduced. The foundation said a transaction could be canceled for insufficient funds while the network still went on to spend those same funds, producing a negative balance that crashed the step where validators reconcile accounts.
What turned one outage into two was the patch itself. The foundation said the interim fix it rushed out Thursday carried a "known issue with a low probability of causing a halt," a risk the team accepted to bring the chain back quickly while a more durable fix was built. On Friday morning, the network hit a variant of that issue and halted a second time.
