Solana Suffers Near 20-Hour Network Outage as Validators Attempt Multiple Restarts

The Solana blockchain experienced a major network outage lasting nearly 20 hours over the weekend of February 25-26, 2023, forcing validators to attempt two separate chain restarts before finally restoring on-chain activity. The incident once again put the spotlight on Solana’s recurring reliability issues, even as the network has positioned itself as a high-performance alternative to Ethereum.

TL;DR

• Solana’s mainnet went offline shortly after midnight on Saturday, February 25
• The network was processing only 93 TPS at one point, far below its usual 5,000 TPS
• Validators attempted two chain restarts over a ~20-hour period
• The root cause of the outage remained unknown as of February 26
• Bitcoin held steady near $23,561 and Ethereum at $1,640 during the incident

The Outage Timeline

According to reports, nearly all on-chain activity on Solana ground to a halt shortly after midnight on Saturday. Users on Solana’s Discord server were among the first to flag issues, reporting that the blockchain had begun unexpectedly “forking” — creating multiple conflicting versions of the chain’s transaction history. This type of forking is particularly dangerous for a network that prides itself on speed and finality.

By approximately 2:00 AM ET, Solana was processing a mere 93 transactions per second, a dramatic plunge from its typical throughput of around 5,000 TPS. For a blockchain that has built its entire brand around being fast and cheap, the contrast was stark.

Validators Rally for Restarts

The Solana validator community sprang into action, attempting not one but two chain restarts over the course of the weekend. Solana’s official status account confirmed on February 26 that the network had been successfully brought back online after the second restart attempt. Engineers from across the ecosystem collaborated to diagnose the issue and coordinate the recovery effort.

However, the root cause of the outage remained under investigation at the time of reporting. The Solana Foundation released a statement acknowledging the incident and promising a thorough post-mortem, but specific technical details about what triggered the forking event were not immediately available.

A Pattern of Outages

This was far from Solana’s first major outage. The network has experienced multiple significant disruptions since its mainnet beta launch, with incidents occurring in September 2021, January 2022, May 2022, and earlier in February 2023. Each outage has reignited debates about the trade-offs between Solana’s impressive throughput capabilities and its reliability record.

Critics on social media were quick to point out the irony of a network marketed as a high-performance blockchain being unable to process basic transactions for nearly a full day. The crypto community, never one to miss an opportunity for gallows humor, flooded Twitter with memes and commentary throughout the outage.

Market Impact and Context

Despite the severity of the outage, broader crypto markets remained relatively stable. Bitcoin was trading around $23,561 and Ethereum held near $1,640, according to CoinMarketCap data from the same date. The total cryptocurrency market capitalization stood at approximately $1.07 trillion.

Solana’s native token SOL experienced some selling pressure during the outage, though the broader market’s resilience helped limit the damage. The incident served as a reminder that even major blockchain networks are still very much works in progress, and that the “move fast and break things” ethos of Silicon Valley has clearly found its way into the crypto ecosystem.

Why This Matters

Solana’s recurring outages represent one of the most significant challenges facing high-throughput blockchains. As the network pushes for greater institutional adoption and expands its DeFi and NFT ecosystems, reliability becomes not just a technical concern but a fundamental trust issue. Users and developers who build on Solana need confidence that the network will be available when they need it. Each outage erodes that confidence and sends developers evaluating alternatives — including Ethereum and its growing roster of Layer 2 solutions. Until Solana can demonstrate sustained uptime that matches its impressive performance metrics when things are working, questions about its long-term viability as a foundational blockchain infrastructure will persist.
