Sui Network, the Layer 1 blockchain developed by Mysten Labs, experienced its first major outage today, temporarily halting transaction processing.
What’s the scoop?
- SUI Bug: The Sui network outage lasted around 2 hours which was caused by a bug in transaction scheduling logic. Validators crashed which halted new block production.
- Update to the Network: A fix was deployed in their v1.37.4 patch and the network is now back up and operational. This is the first major issue on Sui mainnet since its launch in 2023. A previous minor outage occurred on its testnet in June.

While chain downtime can dent confidence in the short term, parallels can be drawn to Solana, which has weathered its own share of outages while maintaining its reputation as a high-performance network. As Sui scales, it may face similar scrutiny but also opportunities to refine its infrastructure and bolster its resilience.
This incident also raises a broader question: Will the market continue to reward projects for pushing technical boundaries, even at the cost of occasional reliability issues? For now, Sui's recovery efforts and its strong developer base signal that the network is well-positioned to bounce back—but the pressure to deliver consistent performance will only grow as it gains traction.
