Points of Focus
- 28.83% of staked SOL stopped voting, just 4.51 percentage points from the finality threshold.
- 597 of 699 staked validators kept voting, while 28.83% of network stake went delinquent.
- AS20326 held 27.34% of staked SOL, with 94% of that stake going offline together.
Solana came within 4.51 percentage points of losing transaction finality on Aug. 12 after 28.83% of staked Solana (SOL) stopped voting. The network kept producing blocks and processing transactions, leaving it 4.51 percentage points from the 33.34% delinquency threshold that would prevent the required two-thirds stake from finalizing blocks.
Solana finality holds despite validator drop
Solana Foundation technology executive Jacob Creech said 597 of 699 staked validators continued voting and affected operators recovered within 40 minutes. Solana’s status page recorded no mainnet incident on Aug. 12 and showed 100% mainnet beta cluster uptime over the previous 90 days.
Last night an infrastructure provider used by some Solana validators had a failure. You probably didn't notice, because the network didn't: blocks kept producing and transactions kept landing.
The facts:
– The Solana network remained operational

Marinade measured delinquent stake at 28.83%, equal to about 86.5% of the 33.34% threshold where finality stops. The staking protocol linked roughly 90 validators to the routing failure and said 59 validators holding 80.2 million SOL returned in the same narrow recovery window. Marinade said the synchronized recovery suggested the validators waited for routing to reconverge rather than switching to backup infrastructure.
1/ Solana got 86% of the way to a halt this morning and it barely registered anywhere.
28.83% of staked SOL went delinquent. Finality stops at 33.34%.
We added up the rewards lost across all 90 affected validators. 333 SOL. pic.twitter.com/EEC2gYwQgz— Marinade 🛡️ (@MarinadeFinance) August 12, 2026
Marinade linked roughly 90 validators to the Teraswitch failure, while Creech’s snapshot showed 102 validators weren’t voting at one point. The measurements differ in scope and timing. Solana’s finality is stake-weighted, making the 28.83% delinquency rate more relevant to consensus than the raw validator count.
Teraswitch outage exposes Solana stake concentration
Teraswitch traced the outage to a malformed default route from its Miami site. A route reflector in Amsterdam propagated it across Europe and Asia-Pacific, leaving 12 sites without a valid forwarding path. Engineers identified the route within 10 minutes and restored service at 04:16:15 UTC.
Marinade reported that AS20326 carried 118.9 million SOL, or 27.34% of total staked SOL, and 94% of that stake went offline together. That 27.34% share sat above the 25% ASN concentration limit used to determine SFDP eligibility. The rule applies to validators seeking foundation delegation and doesn’t cap how much total Solana stake can sit on one ASN. Creech said SFDP validators were unaffected.
By 18:29 UTC on Aug. 12, Teraswitch had deployed the configuration change across all compute sites, while the defect behind the malformed MIA1 route remained unresolved.
