Record // OUTAGE PLAYABLE TEARDOWN
MOUNT RESTART
The network went down. Then down again. And every time, it clawed its way back.

Solana's outage era has a real ledger. Sep 14, 2021: bot traffic from the Grape IDO — roughly 400,000 transactions per second at peak, 'in effect, a denial of service attack' per Solana's own post-mortem — took the network down for about 17 hours. Apr 30–May 1, 2022: NFT-minting bots hammering Candy Machine (millions of requests per second, per later analyses) forced a ~7-hour restart. Jun 1, 2022: a durable-nonce bug caused one transaction to be processed twice, breaking consensus for ~4.5 hours. Sep 30, 2022 brought another halt, and on Feb 25, 2023 the network fell into a degraded vote-only mode that stalled economic activity for roughly 19 hours. The last full halt: Feb 6, 2024, about 5 hours, an infinite JIT-recompile loop in a legacy loader. Each time, over a thousand validators coordinated a restart from a snapshot — and no user funds were lost.
Why Solana remembers it
Mount Restart is a scar and a proof point at once. Every fall forced a structural fix — QUIC ingress, stake-weighted transaction quality-of-service, local fee markets, patched runtimes — and the record shows the hardening worked: as of mid-2026, Solana's official status page has logged no full network halt since February 2024, over two years of uninterrupted block production. These were liveness failures, not hacks — the ledger never lied, it just paused.
