Solana Came Within 4.5 Points of a Finality Halt on August 12
- —28.83% of stake went offline against a 33.34% finality-halt threshold
- —Finality stalled for about 30 minutes versus the usual 13 seconds
- —Share of scheduled slots producing no block jumped from under 1% to over 32%
- —The fault began at TeraSwitch in Miami and hit validators in five cities
Why it matters: The incident shows hosting concentration can stall finality without any attack, a risk the Alpenglow upgrade on October 21 does not address.
