Sui network back online after ~6-hour consensus outage halted transactions

Sui’s Layer-1 blockchain resumed full operation after a 5 hour 52 minute consensus outage that halted transactions and affected more than $1 billion in on-chain value. The Sui Foundation and core developers diagnosed the problem as a stalled consensus process that prevented new blocks from being committed, implemented fixes and coordinated a restart of validators. The incident began being investigated at 14:52 UTC and was resolved at 20:44 UTC. No protocol-level exploit or lost funds have been reported. This is Sui’s second major outage since launch (the prior large incident occurred in November 2024). SUI’s token showed brief volatility — spiking about 4% during the outage and later returning to roughly $1.84 — highlighting short-term market sensitivity. The foundation advised users to refresh apps or browsers if they still experienced issues. For traders, the outage raises reliability concerns for Sui that may prompt validator upgrades or emergency patches; expect possible short-term volatility in SUI but limited long-term fundamental damage given the absence of a security breach.
