Has Solana ever gone down?

Yes, Solana has gone down. The network has a history of full halts, when no new blocks are made until validators coordinate a restart. As of November 2026, though, the last complete outage was in February 2024, more than 1,000 days earlier.

What are the biggest Solana outages in history?

These are the major halts described in Solana Foundation reports:

• September 14, 2021: Bots flooded the network during a token sale on Raydium. The Foundation called it effectively a denial of service attack. Validators ran out of memory and could not agree on the chain's state. The network was offline for about 17 hours and restarted after more than 1,000 validators applied a fix.
• June 1, 2022: A bug in the durable nonce feature let one failed transaction be processed twice. Validators split over which block was valid, and block production stopped for about four and a half hours.
• February 6, 2024: A bug in the code that loads programs caused an endless loop and halted consensus for 4 hours and 46 minutes. The Foundation said all funds were safe.

These were not the only stoppages. The same 2024 report put uptime at 99.94% for the 12 months to February 29, 2024, and cited a 309-day unbroken run that began on February 25, 2023.

Why does Solana go down?

The causes fall into a few groups. Some outages came from floods of transactions that overwhelmed validators. Others came from bugs in validator software. Because most validators long ran software from the same family, one bug could stop a majority at once.

Restarts are also hard. Solana needs a supermajority of stake to agree before it moves forward, so after a halt, operators around the world must coordinate on the same fixed version and restart from the same point.

Infrastructure is a newer risk. On August 12, 2026, a routing error at a Miami data center run by Teraswitch knocked about 90 validators, holding roughly 28.83% of staked SOL, offline, according to staking platform Marinade. Solana stops finalizing blocks if more than about 33.34% is lost. The network came close but did not halt.

How can you check Solana network status?

The official page is status.solana.com. It tracks the Mainnet Beta cluster, public RPC nodes in the US, Europe and Asia, the Explorer and solana.com, with a 90-day uptime history. Between October 23 and November 6, 2026, it listed no incidents.

If the page shows everything working but an app fails, the problem is often the app, wallet or RPC provider, not the chain. A blockchain explorer will show whether new blocks are still arriving.

What has changed since the last outage?

Two shifts stand out. More validators now run a second independent client, covered in what is Firedancer, so one software bug is less likely to hit everyone. And in October 2026 the network switched to new consensus rules, which Solana says tolerate 20% malicious stake plus 20% offline stake, as explained in what is Solana Alpenglow.
