Why Does Solana Go Down? Outage History & Reliability
Bottom line: past outages, now moving toward resilience through diversification
Solana has experienced several temporary network halts in the past. The most recent major full outage was on February 6, 2024 (about 5 hours), and no large-scale full outage has been confirmed since. Client diversification through the independent client Firedancer is seen as the key to further improving resilience.
Key takeaways
The main outages were in September 2021 (halted by a flood of transactions), 2022 (multiple times), and February 6, 2024 (about 5 hours due to a program-cache bug). The causes were mainly congestion and specific bugs. Countermeasures include fee-market improvements and network tuning, plus Jump Crypto's Firedancer, a second client intended to reduce the risk that "a bug in a single implementation halts everything." For the basics, see What is Solana.
History of major outages
| Period | Overview (per reports and official information) |
|---|---|
| September 2021 | Resource overload from a flood of transactions (bots) caused a long outage |
| 2022 (multiple times) | Outages occurred due to congestion and consensus-related issues |
| February 6, 2024 | A validator program-cache bug caused an ~5-hour outage; restored via manual restart |
Since February 2024, no large-scale full outage has been confirmed, and a period of stable operation has continued (check the latest operational status on Solana Status).
Why it went down
The main causes of past outages were generally one of the following:
- Congestion (a flood of transactions): popular token launches and bot-driven mass transactions strained resources
- Specific software bugs: all nodes using the same client hit the same defect, halting consensus
What Firedancer changes
Firedancer is an independent second validator implementation developed by Jump Crypto (a separate implementation from the existing main client). If multiple independent clients are running, a bug in one can be offset by the other continuing to operate, which is expected to reduce the risk of a full outage. Client diversification is an important initiative that moves the network toward greater stability.
What users should know
- During an outage, transactions may temporarily fail to go through (stay calm and check official information)
- Past outages are partly a trade-off of the "fast and cheap" design

FAQ
- Why did Solana go down?
- The main causes are congestion from a flood of transactions and specific software bugs that hit all nodes using the same client. The February 6, 2024 outage was caused by a program-cache bug and lasted about 5 hours.
- Does it still go down often?
- No large-scale full outage has been confirmed since February 6, 2024, and a period of stable operation has continued. You can check the latest status on Solana Status.
- What is Firedancer?
- It is an independent second validator implementation developed by Jump Crypto. Running multiple independent clients aims to reduce the risk of a full outage caused by a bug in one of them.
- What happens to users during an outage?
- Transactions may temporarily fail to go through during an outage. Your assets themselves do not disappear, but stay calm and check official information until service is restored.
