Solana Network Nearly Froze After Routing Error Took 29% of Stake Offline

A newly detailed Teraswitch failure temporarily removed 29% of Solana’s network stake from operation after a routing error, according to CryptoSlate. The incident remained below the threshold required for Solana to halt finality completely, but independent telemetry indicated that the network experienced delayed finality and a sharp reduction in throughput. The episode highlights how a problem affecting a single infrastructure provider can place significant operational pressure on a proof-of-stake blockchain, even without triggering a full finality halt. CryptoSlate reported the details on Sept. 16, 2026. The available information does not indicate that Solana fully stopped confirming transactions, but it does point to a period of materially weaker network performance while the affected stake was offline.
