Sui Outages After v1.72 Crash Bugs: Major Upgrade Restores Network
Sui outages hit the network for 15+ hours over two days after crash bugs were introduced in the Sui 1.72 software update. The Sui Foundation says a major upgrade has now fixed the underlying issues and, per the uptime dashboard, all systems are operational as of Monday.
The outages followed a Thursday incident and two additional Friday halts (nearly 6 hours, then 8 hours 25 minutes, plus a 43-minute outage). The crash bugs involved gas charging: when a transaction failed due to low balances, the system could charge funds first, cancel the transaction second, and create negative balances that caused validator crashes. An interim patch restored the chain, but carried a low-probability risk of another halt.
The Foundation stressed no user funds were at risk and the network did not revert committed transactions after recovery. Validators have also fully addressed a related “randomness-state” bug after restarts.
Market impact: SUI fell from about $0.99 before the outages to around $0.88 by Monday (~-11%). Traders may watch for Sui reliability follow-through and whether similar outage patterns recur, as past incidents have historically increased volatility.
Bearish
The immediate price reaction to Sui outages was negative (about -11% from ~$0.99 to ~$0.88). Even with “no funds at risk” and “no rollback” assurances, the event highlights operational fragility tied to a recent software release, which can revive sell pressure and increase short-term uncertainty.
In the short term, traders are likely to demand proof that the major upgrade fully prevents recurrence of the same validator crash triggers (gas charging/negative balances and the randomness-state restart handling). In the longer term, confidence may recover if monitoring shows stability, but the reliability narrative is damaged for now—especially given that similar outage patterns have appeared in prior periods.
