Solana continued producing blocks on Aug. 12 despite an infrastructure failure that stopped validators representing nearly 29% of network stake from voting. The disruption began at Teraswitch, which the Solana Foundation described as the network’s largest infrastructure provider. A stale default route on a Miami edge router, activated during routine transit-provider maintenance, spread across Teraswitch’s network after transposed routing-policy values applied a no-export instruction toward Europe and Asia-Pacific. Twelve sites lost Internet and inter-site connectivity, including locations hosting Solana validator and RPC nodes. Metrika, an independent blockchain-risk monitoring firm, recorded skipped slots above 32%, non-vote transaction throughput below 300 per second versus roughly 1,100 to 1,300 normally, and about half an hour in which new blocks had not reached finality (the point when transactions become irreversible). The backlog finalized as connectivity returned. Solana needs more than 66% of stake voting to maintain consensus finality, while the offline share remained about 4% to 5% below the corresponding 33% halt threshold. The Solana Foundation said Teraswitch hosted 38% of network stake in 2025 and that its team reduced the provider’s share below 30% before the outage. Teraswitch later hardened its infrastructure so invalid routes cannot prevent sites from using healthy local edge routers, while additional route monitoring remained in progress.
