Sui’s Second Outage Rattles Holders
For the second day in a row, the Sui blockchain suffered a network stall, halting transactions and leaving users and developers in limbo. On Thursday morning, Sui’s mainnet was offline for nearly six hours—5 hours and 55 minutes—before validators received a fix to restore operations. The incident mirrored a similar outage from January 2024, which also saw the network grind to a halt for over six hours due to validator issues.
The root cause this time was traced to a bug introduced in Sui’s “1.72 release,” specifically involving the new Address Balances feature and its interaction with gas charging logic. According to cointelegraph.com, the bug triggered the outage that left the network nonfunctional until a patch could be deployed. This technical stumble is not isolated: Sui has now experienced multiple major outages within just a few months of each other.
Token Slides as Bugs Surface Again
The repeated downtime has taken a toll on SUI, the native token of the blockchain. In the wake of Thursday’s outage, SUI dropped 5.4% in just 24 hours to $0.92. Over the course of the week, losses deepened, with SUI down 20% and recently trading at $0.89—far from its January 2025 all-time high of $5.35.
This price collapse means SUI has lost more than 83% of its value since peaking earlier in the year. Despite boasting a market capitalization near $3.6 billion, these numbers underscore how quickly sentiment can turn when technical reliability is in question.
On paper, Sui’s valuation remains robust—but its token performance tells another story.
Patch Deployed, But Doubts Remain
After nearly six hours offline on Thursday, an update rolled out to validators allowed transaction processing to resume. The fix targeted interactions between new address balance tracking and gas fee logic introduced in the latest software release. While this brought relief to users awaiting pending transactions, it did little to quell broader concerns about network stability.
Sui’s January stall had already raised eyebrows; with two major outages now occurring within months—and on consecutive days—the reliability of core updates is under scrutiny. Developers face mounting pressure to ensure future releases are thoroughly tested before deployment across mainnet validators.
$300M Backing, But Network Stumbles
Mysten Labs launched Sui in 2023 after spinning out from Meta’s Diem project. Backed by a $300 million Series B funding round in 2022 that valued the company at $2 billion, expectations for technical excellence were high from day one. Yet despite this substantial war chest and high-profile pedigree, persistent outages have cast doubt on whether funding alone can guarantee reliability.
The network’s rapid growth and ambitious roadmap have been overshadowed by repeated stalls that directly impact user trust and token price stability. For many holders and developers, questions linger: Will Sui’s engineering team address these recurring bugs before they erode confidence further?
It’s unclear how quickly Mysten Labs can restore faith among stakeholders after back-to-back disruptions.
Key risks to monitor
If another outage similar to the 5-hour, 55-minute downtime caused by the 1.72 release bug recurs in the coming days, especially after two consecutive days of network stalls, immediate further pressure on the SUI token—already down 20% this week and trading at $0.89—would be likely; whether the latest patch fully resolves the validator issues remains unclear.
