A Fidelity assessment says Solana has recorded no reported mainnet outages over the past two years, while noting that stake, hosting and client-software concentration still warrant continued observation.

Cointelegraph reported on Oct. 17, 2026, that a Fidelity assessment credits Solana with two years without a reported mainnet outage. That is a notable operational record for a layer-1 blockchain designed for high-throughput applications. The report does not treat uptime alone as a complete measure of resilience, however. It also points to concentration in staking, hosting and client software as areas requiring continued observation. This combination sets the tone for the review: a strong outage record alongside structural risks that may not appear in uptime statistics.
The report highlights concentration in stake as one of the areas to watch. In a proof-of-stake network, the distribution of staked tokens affects how much influence validators have over block production and consensus participation. If a large share of stake is held by a small number of validators or delegation pools, operational risk can become clustered. Fidelity's point is not that a failure has occurred, but that the distribution deserves ongoing scrutiny as part of a resilience review. For Solana, this makes decentralization metrics relevant alongside performance measures.
Fidelity also flags hosting concentration, a risk that sits outside the protocol's code. When many validators rely on a limited set of cloud providers or data centers, a provider outage, policy change or regional disruption can affect multiple nodes at once. That creates a shared failure point even if the blockchain software itself is functioning as intended. The issue is common across blockchain networks, but its importance rises when a network's validator set is already concentrated. By including hosting in its review, Fidelity links network resilience to real-world infrastructure dependencies.
The third area Fidelity identifies is concentration in client software. If most validators run the same client implementation, a bug or faulty upgrade in that software could affect a large portion of the network simultaneously. Client diversity is therefore treated as a resilience factor: multiple implementations can reduce the chance that one software issue becomes a network-wide event. The report's inclusion of this point shows that Solana's two-year outage record is only one input in assessing operational strength. Based on public news sources.
Fidelity's assessment notes that Solana has had no reported mainnet outages in two years, according to Cointelegraph. It also says concentration in stake, hosting and client software should continue to be monitored. The report therefore presents resilience as both an uptime record and an ongoing operational-risk question.
In proof-of-stake systems, staked tokens influence how much weight validators have in block production and consensus participation. If a large share of stake sits with a small number of validators or delegation pools, operational risk can become clustered. Fidelity's report treats this distribution as a factor to watch rather than as evidence of a current failure.
Hosting concentration means that many validators depend on a limited set of cloud providers or data centers. If one provider suffers an outage, policy change or regional disruption, multiple nodes could be affected at the same time. This makes hosting an infrastructure risk that is separate from the blockchain's software code.

Hosting Dependencies Can Create Shared Failure Points
Client Software Diversity Is Part of the Risk Picture
What the Assessment Does and Does Not Establish

The report's central finding is balanced: Solana has avoided reported mainnet outages for two years, but concentration risks remain part of the operational picture. It does not present an outage-free record as proof that all risks are resolved. Instead, it separates uptime from structural concentration, which can remain latent even when the network is running normally. That distinction helps explain why resilience reviews often combine performance data with infrastructure and decentralization analysis. The report frames Solana's resilience as a continuing assessment rather than a one-time label.
If most validators run the same client implementation, a bug or faulty upgrade could affect a large portion of the network at once. Client diversity is viewed as a resilience factor because multiple implementations can limit the impact of a single software issue. Fidelity's report includes this as one of the concentration areas requiring continued observation.
No. An outage-free record is one indicator of network performance, but it does not resolve structural risks such as stake, hosting or client-software concentration. Fidelity's assessment keeps those areas in view even while acknowledging Solana's recent uptime record. The report therefore treats resilience as a continuing review rather than a final verdict.
