Sui Restores Service After Major 6-Hour Outage Shook Network
Sui’s blockchain resumed normal activity after a network stall that halted transactions for roughly six hours on January 14, 2026. According to reports, validators identified the problem in the mid-afternoon and worked to roll out a fix that restored block creation and transaction processing later that evening. Sui launched mainnet in May 2023, and this outage follows previous incidents that raised similar questions about validator coordination and uptime. One earlier major disruption occurred in November 2024, which also involved issues around consensus and validator operation. Developers who build on Sui said many of their services experienced interrupted user flows while the chain was stalled.Past Interruptions And Context
