The Solana network encountered a significant disruption on February 6, leading to a temporary halt in block production, a situation that sparked immediate action from validators within the ecosystem.
The outage, identified at 10:22 UTC, represented a stark deviation from Solana’s typical block production pace, causing concern among users who noticed the prolonged inactivity.
Urgent Response and Recovery Efforts
In response to the network stall, Solana validators, in collaboration with developers, embarked on a comprehensive strategy to rectify the issue.
Stakewiz, a prominent validator, highlighted the community’s efforts to construct and test a new release aimed at resolving the outage.
This proactive approach involved validators creating snapshots based on their local ledger states, a critical step toward facilitating a network restart.
Technical Measures for Restoration
The restoration plan centers around the production of snapshots for slot 246464040, ensuring the integrity of the bank hash for this specific slot.
The consensus among validators to restart the Mainnet-Beta cluster with version 1.17.20 represents a unified approach to overcoming the technical challenge.
Snapshots are a point in time representation of the global Solana state at a specific slot. The last optimistically confirmed slot is the last slot all validators have processed and has been confirmed by a supermajority but is not finalized, by using this slot we ensure no…

The Solana team has confirmed the absence of state inconsistencies, signaling readiness for a coordinated restart upon final approval from core engineers.
The Role of Snapshots in Recovery
Snapshots play a pivotal role in the recovery process, offering a point-in-time capture of Solana’s global state at a predetermined slot.
These snapshots enable validators to align on a specific ledger state, ensuring transaction continuity and preventing potential rollbacks.
The introduction of version v1.17.20 further underscores Solana’s commitment to network stability, providing validators with the necessary guidance to upgrade and initiate a restart.
Broader Implications of the Outage
The recent network outage has broader implications, particularly for crypto exchanges like Upbit, which announced temporary suspensions of deposits and withdrawals for Solana-based tokens.
This incident marks the latest in a series of outages that have challenged Solana since its inception in March 2020.
Despite its ambition to offer a scalable, decentralized ecosystem with competitive transaction speeds and costs, Solana has faced ongoing operational hurdles, necessitating multiple network restarts.
Moving Forward: Solana’s Resilience and Recovery
As Solana navigates through its eleventh outage in two years, the community’s swift response and collaborative recovery efforts underscore a resilient commitment to maintaining network integrity.
The focus on enhancing stability and reliability continues to be paramount as Solana strives to fulfill its vision of a scalable and efficient blockchain ecosystem.
