• Chainlink experienced no downtime during the AWS outage, unlike many other blockchain systems.
• The network’s decentralized architecture and uptime focus enabled uninterrupted oracle and cross-chain operations.
• Chainlink has supported over $26 trillion in transaction value through consistent performance during market and infrastructure disruptions.

During a recent disruption at Amazon Web Services (AWS), Chainlink’s infrastructure remained fully operational, according to Sergey Nazarov. While several blockchain systems experienced service failures, Chainlink’s decentralized oracle network continued to operate without downtime. Nazarov attributed this performance to the network’s structural design and long-standing emphasis on reliability.

Chainlink Maintains Stability as Others Falter

In his recent remarks, Nazarov reported that many blockchain-based systems, including oracles and bridges, went offline during the AWS outage. Despite their claims of decentralization and high reliability, these systems were impacted significantly. Chainlink, however, maintained uninterrupted service across all operations.

He explained that Chainlink’s architecture supports resilience through a network of independent node operators and diversified data sources. This setup reduces the reliance on any single cloud provider, including AWS. According to Nazarov, Chainlink continued to deliver oracle data and operate cross-chain bridges during the AWS downtime. 

The network provides oracle services on major blockchains, including Ethereum, where it supports the majority of data feeds. These oracles remained active throughout the outage. The consistent operation extended to Chainlink’s cross-chain services, where data transmission and bridging functions experienced no interruptions. Nazarov pointed out that this reliability has been demonstrated repeatedly during industry-wide outages and market events.

Resilience Linked to Network Design and Uptime Guarantees

Nazarov credited the uninterrupted performance to Chainlink’s design principles and focus on uptime guarantees. He said Chainlink’s reliability has remained consistent even as the network expanded into new service areas. The system’s ability to stay online during infrastructure failures was described as a core requirement for handling financial and contractual data. 

Nazarov explained that systems managing value cannot afford downtime and must operate through disruptions. Chainlink has enabled over $26 trillion in transaction value through its oracle and cross-chain services, Nazarov stated. He emphasized that this level of usage depends on consistent performance, especially during service disruptions that impact other providers.

The network’s ability to scale while maintaining availability was presented as a key factor behind continued adoption. According to Nazarov, as Chainlink’s functionality grows, its uptime must remain constant to support that expansion. Nazarov referenced the AWS outage as the latest example of Chainlink operating through cloud-level failures. While many decentralized services experienced disruptions, Chainlink’s infrastructure reportedly stayed fully functional throughout the incident.
