Marinade Says Routing Fault at One Hosting Provider Took 28.83% of Staked SOL Offline

Solana came close to losing transaction finality early Wednesday after a routing misconfiguration at hosting provider Teraswitch knocked 28.83% of staked SOL offline, according to staking platform Marinade. The firm said Solana stops finalizing at 33.34%, leaving the network about 86% of the way to a freeze during the incident. Marinade traced the issue to a default route from Teraswitch’s Miami site that spread across facilities in Europe and the Asia-Pacific region. It said autonomous system AS20326 alone carried 118,890,767 SOL, more than a quarter of all staked SOL and above the 25% cap used by the Solana Foundation’s delegation program, with 94% of that stake going dark at the same time. Another 14.1 million SOL dropped offline across latitude.sh, Limestone, Butterfly Research and Allnodes for reasons Marinade said it could not explain from the available data. Marinade added that failover barely activated, Helius was down for the full 33 minutes, and only three of 74 operators it could measure recovered cleanly. Solana Foundation VP of Tech Jacob Creech disputed the framing, saying the chain kept producing blocks, 597 of 699 staked validators kept voting, affected validators recovered within 40 minutes, and validators in the Foundation delegation program were not affected.
