Marinade Finance disclosed that the Solana network came close to stalling on the morning of August 12, after 28.83% of staked SOL lost connection — approaching the 33.34% threshold that would trigger a halt. The incident involved 90 validators and cost roughly 333 SOL in rewards. Marinade traced the root cause to a routing error at infrastructure provider Teraswitch: an erroneous route from a Miami node was broadcast to Europe and Asia-Pacific, knocking out 12 nodes across London, Amsterdam, Dublin, Frankfurt, Singapore and Tokyo. North America was unaffected, and the issue was fixed within 10 minutes. Marinade also flagged a concentration risk: ASN AS20326, which hosts more than a quarter of all staked SOL, saw 94% of its nodes go offline simultaneously, pushing the actual offline share to 27.34% — above the 25% cap set by SFDP. Helius, the network's second-largest node, stayed offline for 33 minutes, and only a handful of validators executed smooth failovers. Marinade said it will review staking concentration limits and push validators to disclose failover capabilities.
Solana came within striking distance of a network halt on the morning of August 12, after a routing error at infrastructure provider Teraswitch knocked out nearly 29% of staked SOL.
Staking platform Marinade Finance said in a post that 28.83% of staked SOL lost connection, approaching the 33.34% threshold that would have triggered a halt. The incident involved 90 validators and cost roughly 333 SOL in rewards.
Routing error at Teraswitch
Marinade traced the fault to a routing error at Teraswitch: an erroneous route from a Miami node was broadcast to Europe and Asia-Pacific, leaving 12 nodes — LON1, AMS1-3, DUB1-2, FRA2, SGP1-2 and TYO1-3 — without a valid route. North American nodes were unaffected, and the issue was fixed about 10 minutes later.
Staking concentration exposed
The episode also highlighted how concentrated Solana's staking has become. Marinade noted that AS20326, an autonomous system number hosting more than a quarter of the network's staked supply, saw 94% of its nodes drop offline at the same time during the fault. That pushed the actual offline share to 27.34%, above the 25% cap allowed by SFDP rules.
Helius, the network's second-largest node, stayed offline for 33 minutes. Only a few validators managed a smooth failover, Marinade said.
Going forward, Marinade said it will review staking concentration limits and push validators to publicly disclose their failover capabilities.
