The South Korean crypto exchange Upbit had temporarily disabled SUI deposits and withdrawals amid the network outage.
Sui, a decentralized layer-1 blockchain designed for rapid smart contract deployment, experienced a significant outage on Nov. 21, halting block production for more than an hour.
The Sui blockchain went down with no blocks being produced for more than an hour, according to data from the Sui Network explorer, SuiVision.
According to the data, the last block occurred at 9:15 am UTC, with no new blocks produced since, at the time of writing.

Multiple industry observers reacted to the downtime, with many outlining Sui’s ambitions to be one of the biggest competitors to Solana SOL$241.61, which is the fourth-largest cryptocurrency by market capitalization.
“SUI blockchain is down. And they claimed to be a Solana Killer,” crypto YouTuber Ajay Kashyap wrote on X.
