Marinade: Service Provider Teraswitch Routing Error Nearly Triggers Solana Downtime This Morning

August 12th, Solana staking platform Marinade Finance tweeted that the Solana network was on the brink of halt this morning: 28.83% of staked SOL experienced a blackout, nearing the 33.34% threshold for triggering a halt, involving 90 validation nodes, with a total loss of approximately 333 SOL rewards. The outage originated from a routing error by the service provider Teraswitch: a Miami node routing error was broadcasted to Europe and Asia-Pacific, causing 12 nodes (LON1, AMS1-3, DUB1-2, FRA2, SGP1-2, TYO1-3) to lose proper routing, while North America remained unaffected, and the issue was resolved 10 minutes later.

Marinade pointed out that AS20326, this ASN hosts over a quarter of the network's total staked amount, with 94% offline simultaneously during the outage, and the actual percentage of 27.34% has exceeded the 25% cap set by SFDP regulations; the network's second-largest node Helius was offline for 33 minutes in full, with only a few nodes achieving a smooth failover. Marinade stated that they will review the staking concentration limit and advocate for validation nodes to publicly disclose their failover capabilities.
