Solana Nearly Halts as TeraSwitch Routing Failure Takes 29% of Staked SOL Offline
On August 12, a routing malfunction at TeraSwitch's facility in Miami nearly disrupted the finality of Solana's network, impacting 29% of staked SOL. This incident was caused by a defective internet route in Amsterdam, which affected data centers in London, Dublin, Frankfurt, Singapore, and Tokyo, while operations in North America remained unaffected. TeraSwitch managed to diagnose the issue within approximately 10 minutes, restoring traffic by 4:16 a.m. UTC. Marinade Finance noted that 28.83% of staked SOL fell into delinquency, close to the 33.34% threshold for losing finality. Approximately 90 validators were impacted, with 597 still participating in voting. The outage lasted for 33 minutes, resulting in a loss of 333 SOL in rewards for those affected. This event underscored the necessity for diverse infrastructure to enhance network security.
