Solana2026-08-13 10:47:33Marinade Says Routing Fault at One Hosting Provider Took 28.83% of Staked SOL OfflineSolana came close to losing transaction finality early Wednesday after a routing misconfiguration at hosting provider Teraswitch knocked 28.83% of staked SOL offline, according to staking platform Marinade. The firm said Solana stops finalizing at 33.34%, leaving the network about 86% of the way to a freeze during the incident. Marinade traced the issue to a default route from Teraswitch’s Miami site that spread across facilities in Europe and the Asia-Pacific region. It said autonomous system AS20326 alone carried 118,890,767 SOL, more than a quarter of all staked SOL and above the 25% cap used by the Solana Foundation’s delegation program, with 94% of that stake going dark at the same time. Another 14.1 million SOL dropped offline across latitude.sh, Limestone, Butterfly Research and Allnodes for reasons Marinade said it could not explain from the available data. Marinade added that failover barely activated, Helius was down for the full 33 minutes, and only three of 74 operators it could measure recovered cleanly. Solana Foundation VP of Tech Jacob Creech disputed the framing, saying the chain kept producing blocks, 597 of 699 staked validators kept voting, affected validators recovered within 40 minutes, and validators in the Foundation delegation program were not affected.1450
Solana2026-08-12 14:13:07Routing Error Pushed Solana Within 4.51 Points of Losing FinalitySolana came close to losing transaction finality on Wednesday morning after a routing mistake at hosting provider Teraswitch sent 28.83% of staked SOL offline. That left the network just 4.51 percentage points away from the 33.34% threshold at which finality stops, or about 86% of the way to a halt. Teraswitch said the issue began when a default route from its Miami site was propagated without its metric and communities, then reflected from Amsterdam into Europe and Asia-Pacific. Edge routers in those regions treated the route as locally originated, preferred it over the valid path, and passed it upstream, where it was rejected. Twelve sites across London, Amsterdam, Dublin, Frankfurt, Singapore and Tokyo were affected, while North America was not. Engineers identified the problem within 10 minutes, and service was restored at 04:16:15 UTC. Post-incident analysis from Marinade Finance found the outage was heavily concentrated in autonomous system AS20326, which carries 118,890,767 SOL and sits above the Solana Foundation delegation program’s 25% cap at 27.34%. Marinade also said 90 affected validators lost 333 SOL in rewards, and warned that stake concentration measured only by hosting provider can miss correlated failures.410
Solana2026-08-12 11:10:30Solana Nearly Stalled After Teraswitch Routing Error Took 28.83% of Staked SOL OfflineMarinade 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.1590
Solana2026-08-12 11:12:54Solana Nears Halt as 28.83% of Staked SOL Goes Offline, Marinade HighlightsMarinade Finance reported early today that Solana nearly stalled after a routing failure at infrastructure provider Teraswitch knocked 28.83% of staked SOL offline. The number sat just below the 33.34% threshold that could trigger a chain-wide standstill. The incident affected 90 validators and cost roughly 333 SOL in rewards. A faulty route from a Miami node spread to Europe and Asia-Pacific, leaving 12 nodes (LON1, AMS1-3, DUB1-2, FRA2, SGP1-2, TYO1-3) without valid routes. North America was unaffected and the problem was fixed within 10 minutes. Marinade also flagged concentration risk around AS20326, an ASN that hosts more than a quarter of all staked SOL. During the failure, 94% of its stake went offline at once, equal to 27.34% of total staked SOL and above SFDP's 25% cap. The second-largest validator, Helius, stayed offline for 33 minutes, with only a few nodes achieving clean failover. Marinade said it will review its staking concentration ceiling and push validators to publicly disclose failover capabilities.1600
