Solana Routing Failure Sparks Near-33% Delinquency Rate

Solana's network came perilously close to a finality halt on August 12 after a routing failure led to nearly 29% of staked SOL going offline. The issue stemmed from a default route advertised by infrastructure provider Teraswitch, which lost its normal routing attributes during propagation and was distributed to sites across Europe and Asia-Pacific.

As a result, twelve sites in locations including London, Amsterdam, Dublin, Frankfurt, Singapore, and Tokyo were left without any valid forwarding path. Teraswitch engineers quickly identified the issue within ten minutes of onset, but it took 33 minutes for traffic to fully recover.

The outage affected around 90 validators, resulting in lost rewards totaling 333 SOL ($76.26) across the affected group. The Solana Foundation Delegation Program's policy caps any single autonomous system at 25% of total network stake, and AS20326 currently exceeds this limit with a share of 27.34%.

Marinade Finance has announced that it will review concentration limits by autonomous system and physical data center, as well as publish information on validators running hot-swap and automatic failover setups.
