In brief
The Sui layer-1 blockchain suffered downtime for the second consecutive day on Friday.
The network has a history of outages, with three significant events this year alone.
Activity on Sui mainnet has resumed after a halt due to a crash bug in the gas charging logic introduced by the 1.72 release. A full incident review will be shared in the coming days.
— Sui (@SuiNetwork) May 28, 2026While a full postmortem of the incident is still to come, the network indicated that its Thursday outage was a result of a bug introduced in its latest release. It’s unclear if Friday’s outage is related to Thursday’s incident or the ensuing patch. A representative for the network nor Mysten Labs, the core team behind it, immediately responded to Decrypt’s request for comment. The outages come just a few months after the firm reported a similar network stall in January, which led to six hours of downtime for the layer-1 blockchain’s mainnet. Hailed as a “Solana-killer,” the network has been plagued with some of the same issues as the speedy layer-1 network, which similarly dealt with major outages in the past. Sui was launched in 2023 by Mysten Labs and raised a $300 million Series B in 2022, giving it a valuation around $2 billion at the time. Even with its recent decline, the network’s token currently trades with a market cap of around $3.6 billion.Daily Debrief NewsletterStart every day with the top news stories right now, plus original features, a podcast, videos and more.
