Sui Network Recovers from Nearly 6-Hour Outage Due to Critical Bug

The Sui Network has successfully resumed operations after a troubling six-hour outage, triggered by a bug in a recent update, marking the second significant disruption for the layer-1 blockchain in 2026. The mainnet went offline for 5 hours and 55 minutes, causing a brief but impactful halt in blockchain activity.

In a post made via X on Thursday, Sui confirmed that its mainnet activity has been restored after a ‘crash bug’ affected the gas charging logic introduced in their version 1.72 update. The company assured its users that a comprehensive incident review will be released in the coming days to clarify the situation.

During the downtime, Sui warned users that the blockchain was experiencing a “network stall,” which caused transactions to be temporarily halted. Despite the resolution of the issue, validators on the Sui mainnet still displayed signs of “degraded performance,” indicating potential lingering challenges.

This latest incident is particularly noteworthy as it marks the second outage for the Sui blockchain this year; the first occurred in January when the network was offline for over six hours. A prior incident back in November 2024 had also raised concerns when all validators were trapped in a crash loop for approximately two and a half hours, preventing any transactions from being processed.

As of now, Sui Network stands as the 13th largest blockchain, boasting a total value locked at $542 million and hosting a diverse array of 137 protocols, according to data compiled by DefiLlama.

In response to the outage, the SUI token experienced a 6.6% drop, falling to a low of 90 cents. However, it has since made a modest recovery, trading at around 93 cents as of early Friday morning. Earlier in the month, the token had surged by 50% to $1.41, driven by positive market developments including a Nasdaq-listed company staking a significant portion of its supply and plans for the introduction of zero-fee stablecoin transfers and private transactions.

Sui Network, launched in May 2023, was designed with scalability in mind and aims to facilitate transaction speeds that meet the demands of financial institutions. Co-founder Adeniyi Abiodun shared exciting news at Consensus 2026, affirming that zero-fee stablecoin transfers are on the horizon, alongside plans for private transaction features.

However, not all disruptions in the cryptocurrency landscape this year have been attributed to technical challenges. In April, the decentralized exchange Drift Protocol faced a hack, leading to a temporary suspension of deposits and withdrawals. Additionally, the liquid restaking protocol Kelp was the target of a cyberattack during the same month, prompting it to pause smart contracts while conducting further investigations.

The recent events surrounding the Sui Network highlight the ongoing challenges faced by the blockchain industry as it strives to offer robust and reliable services to its users in a rapidly evolving market.
