Overview
- On Wednesday, roughly 28.83% of staked SOL went offline for about 33 minutes after a malformed default route propagated from Teraswitch’s Miami site to data centers in Europe and Asia.
- The outage stopped short of the 33.34% delinquency line that would halt transaction finality because engineers found the fault in about ten minutes and normal traffic returned by 04:16:15 UTC.
- Marinade’s analysis showed a single autonomous system, AS20326, held about 27.34% of staked SOL and that roughly 94% of that stake lost connectivity at once, exceeding the Solana Foundation Delegation Program’s 25% cap.
- Most affected validators did not trigger hot-swap or automatic failover during the event, with about 90 validators losing a combined 333 SOL in rewards that will be covered by validator bonds.
- The incident has triggered operational and policy responses: Teraswitch deployed a configuration fix and published a postmortem, and Marinade said it will review allocation limits by AS and data center and disclose validators’ failover setups as part of broader resilience work.
