Solana network performance degraded after routing error impacted 29% of stake

The Solana network experienced a significant performance decline on Aug. 12 due to an infrastructure failure at Teraswitch, its largest provider. A stale default route on a Miami edge router caused connectivity issues for twelve sites across Europe and Asia-Pacific, preventing validators representing nearly 29% of the network stake from voting. While the chain avoided a total halt, block production continued with increased skipped slots, reduced transaction throughput, and delayed finality. Connectivity was restored 33 minutes after the initial alarm, allowing the backlog to finalize.
