Solana network stake drops 29% due to routing error

On August 12, the Solana network continued block production despite an infrastructure failure that prevented validators representing nearly 29% of the network stake from voting. This disruption, traced to a stale default route on a Miami edge router by Teraswitch, Solana's largest infrastructure provider, led to increased skipped leader slots and a significant drop in transaction throughput. Independent monitoring by Metrika confirmed that skipped slots rose above 32% and non-vote transaction throughput fell below 300 per second, down from the typical range of 1,100 to 1,300. The outage affected twelve sites across Europe and Asia-Pacific, disrupting connectivity for Solana validators and RPC nodes. Although Solana avoided a complete production halt, users experienced weaker performance due to delayed settlement finality. Teraswitch, which previously hosted 38% of network stake, reduced its share below 30% before the incident. The company implemented measures to prevent similar failures in the future, including route monitoring and infrastructure diversity.
