The Sui network was paralyzed for over five hours yesterday, May 28, when a bug in software version 1.72 stopped processing all transactions, according to the team behind the network. The SUI token, the network’s native currency, fell 6.25% on the day from $0.96 to a low of around $0.90.
The developer team warned about the issue in their first post on X, stating, “Sui mainnet is experiencing downtime. Sui’s core team is actively working on a solution. Transactions may be suspended at this time.”
Later, in a second article published after the resumption, he identified the cause: “Activities on the Sui main network have resumed after being stopped due to the cause. Critical bug in gas filling logic introduced in version 1.72.»
The Gas Charge module is a software component that automatically calculates and deducts fees before processing each transaction. If that module fails with a crash error, an error that causes the program execution to suddenly stop instead of processing and continuing. Node cannot proceed to next blockIf that happens simultaneously to the validators holding the network, processing will stop completely. That was the mechanism that paralyzed Sui.
According to the publication, the team announced it would share a “full review of the incident in the coming days” without specifying a date.
This is not the first time Sui has quit her job.
In November 2024, The network has gone more than 2 hours without producing a block after failure. At the time, the SUI token fell over 7% on the day, as reported by CriptoNoticias.
Similarly, this pattern was repeated in January 2026. Several hours of new arrests have been confirmed by network developers.
The cumulative effect of at least these three disruptions raises questions about the operational resiliency of the network in a segment where Sui competes with other chains such as Solana, Aptos, and Avalanche. Use processing power as the central argument.
