On November 21, 2024, the Sui Network—a new layer-1 platform and potential 10x famous for its swift smart contract rollouts—experienced a two-hour network outage. Uh-oh.
We’ve spent much of this year praising Sui as the ‘next Solana,’ but is it also the next Solana in terms of network outages?
The surprise outage paused block production for over an hour, stirring worries and chatter about its dependability and what’s next.
Understanding the Cause of the Sui Network Outage
The disruption in the Sui blockchain’s operations was traced back to a bug in the transaction scheduling logic. This bug caused validators to crash, resulting in a temporary halt in block production. Cryptocurrency security firms, including ExVul, identified the issue as a DOS (Denial of Service) bug due to integer overflow. ExVul further pointed out the potential bug location on GitHub, which helped in formulating a quick fix.
The outage affected block production and had a significant impact on the blockchain’s native cryptocurrency, SUI. The token experienced a sharp decline of nearly 11%, dropping to around $3.36.
Big ouch for any bagholders out there. (Me! Guilty as charged)
Despite this setback, SUI remained up 75% over the past month, indicating resilience in the face of adversity.
Major exchanges, like South Korea’s Upbit, responded by temporarily suspending SUI deposits and withdrawals to safeguard users against potential disruptions. This move underscored the interconnected nature of blockchain reliability and cryptocurrency market stability.
The Sui Network’s Response To Down Time
The Sui network is back up and processing transactions again, thanks to swift work from the incredible community of Sui validators.
The 2-hour downtime was caused by a bug in transaction scheduling logic that caused validators to crash, which has now been resolved. https://t.co/TJh2zwvQcD

This was Sui’s first big hiccup on the mainnet, but earlier in 2024, the testnet saw similar bumps—network downtime and RPC node crashes that got fixed in a jiffy.
Lessons learned, and hopefully Sui can prevent more outages in the future. Because if not, why not just invest in Solana?
Tim Kravchunovsky, founder and CEO of the Sui-based decentralized network Chirp, noted that glitches are just part of the blockchain landscape, much like any internet outage. He remarked that while downtime is undesirable, it mirrors the occasional disruptions we experience with internet connectivity.
“Any blockchain aims to avoid such incidents entirely, but sometimes outages are unavoidable,” Kravchunovsky noted.
Looking Ahead For Sui Crypto After Outage
Moving forward, Sui’s ability to maintain network stability, coupled with transparent communication, will be crucial in building trust among users and investors.
As the blockchain landscape continues to evolve, Sui’s experience with this outage will likely inform its path toward greater reliability and innovation.
