Sui, a decentralized layer-1 blockchain, experienced a significant outage on November 21, halting block production for over an hour. According to SuiVision data, no blocks were produced after 9:15 UTC. This calls into question Sui’s ambition to compete with major rivals like Solana. The outage caused an 11% drop in the value of the SUI token. The Sui Foundation announced that they have identified the issue and will fix it shortly. ExVul stated that the outage was caused by a DOS error.
