The Sui blockchain suffered three separate failures in 48 hours due to gas calculation bugs and validator synchronization issues.
Were these outages indications of more serious architectural issues or just uncommon edge cases?
Sui, a leading Layer-1 blockchain, experienced three separate mainnet outages on May 28 and May 29, 2026, after a series of software bugs triggered network-wide disruptions. According to a post-mortem released by the Sui Foundation, each attempted fix either revealed or contributed to another failure, resulting in a cascading reliability incident that temporarily halted blockchain operations.
The Sui blockchain encountered an unprecedented series of network failures last week, experiencing three complete shutdowns within a 48-hour window. This Layer 1 protocol, developed by Mysten Labs, remained non-operational for a cumulative period exceeding 18 hours throughout May 28 and May 29.
Sui says a major upgrade fixed bugs behind three outages that halted mainnet activity for over 15 hours while user funds stayed safe Monday.
Sui Foundation disclosed that three separate mainnet interruptions on May 28-29, 2026 were caused by upgrade-related bugs, including flaws in gas charging logic introduced with the v1.72 release and a latent issue with how validators preserved randomness state across restarts. No user funds were at risk and no committed transactions were reverted, the foundation said.
SUI, ONDO, and Pi Network are attracting investor attention as some of the most undervalued crypto coins to watch in 2026. Despite recent market volatility, traders continue monitoring these digital assets for potential recovery opportunities driven by network developments, support levels, and ecosystem growth.
