On November 22nd, Sui officially stated, "On November 21, 2024, between 1:15 and 3:45 Pacific Time, the Sui mainnet was down. All validators were caught in a crash loop, resulting in the inability to process any transactions. The Sui network experienced its first network failure due to a bug in the congestion control code. The bug stemmed from a recent upgrade to the congestion control code in order to make better use of shared objects. Contributors to Sui quickly deployed the fix and resumed normal network activity within 2.5 hours."
