Sui network temporarily stalls again after Thursday's outage
Sui stalled again on Friday after Thursday’s outage, with the team blaming the same 1.72 software update bug.
Intelligence analysis by GPT-5.4 Mini
Sui’s mainnet briefly stopped making blocks for a second day in a row after a software update bug resurfaced. The team said the earlier fix was only temporary and that a longer-term fix has now been deployed by most validators.
Sui is like a big shared notebook that many computers help keep updated. On Friday, that notebook stopped getting new pages for a while, just like a printer jam.
The people running Sui said the trouble came from a software update that changed how some fees and account balances worked. They first used a quick patch, but it did not fully solve the problem.
A better fix is now in place for most of the helpers. The story matters because people want a money network to keep working smoothly, the same way they want a train to stay on schedule.
Analysis
What happened
Sui experienced another network stall on Friday, May 29, 2026, after already suffering an outage on Thursday. According to the Sui team, the disruption temporarily halted block production before normal activity resumed. The article says the network stall had lasted for more than three hours and 30 minutes at the time of publication.
The last block before the disruption was produced at about 11:51 UTC, and the network resumed around 3:30 UTC, according to Suiscan and the Sui team. Sui said both halts were tied to the 1.72 release, which introduced address balances and gas charging logic. The team added that Thursday’s fix was only an interim measure meant to restore functionality.
Why the second halt matters
The article frames this as a repeat of a broader reliability problem. Thursday’s outage was described as a nearly six-hour disruption caused by a crash bug in gas charging logic. The Friday stall suggests the first workaround did not fully eliminate the underlying issue, even if the team said the interim fix had a low probability of causing another disruption.
The team said a long-term software fix has now been implemented by a majority of Sui validators. The story also places the incident in context: Sui had another major outage in January 2026, when the network went offline for more than six hours because of a consensus bug.
Broader context
The article notes that outages can happen in crypto systems with high throughput because they rely on multiple layers, including execution and validator consensus. It also points out that even centralized services can suffer outages, citing Coinbase’s temporary disruption during an AWS outage in May.
