Infura is a powerful infrastructure platform that enables decentralized applications (dApps) and cryptocurrency exchanges to seamlessly connect to the Ethereum blockchain—without the need to run their own local nodes. On November 11, multiple users reported service disruptions across major crypto platforms including Binance, Upbit, and Bithumb, which temporarily halted deposits and withdrawals for ETH and ERC20 tokens. At the same time, the popular Web3 wallet MetaMask experienced delayed transaction data and incorrect balance displays.
The root cause? Infura, the widely used API provider for Ethereum and IPFS, confirmed an outage in its Ethereum Mainnet API services. Their team was actively investigating and working to restore full functionality.

This incident sparked widespread discussion: What exactly is Infura? How did one service bring so many platforms to a standstill? And what does this mean for the decentralization ethos of Web3?
Understanding Infura: The Backbone of Web3 Development
At its core, Infura is an Infrastructure-as-a-Service (IaaS) solution specifically designed for Ethereum developers. It provides a managed cluster of Ethereum nodes that allow developers to deploy smart contracts, query blockchain data, and interact with the network—without setting up or maintaining their own full nodes.
To put it simply: Infura acts as a gateway between your dApp or exchange and the Ethereum blockchain. Instead of downloading and syncing a full node—which can take days due to the ever-growing blockchain size—developers rely on Infura’s high-performance, globally distributed API endpoints.
This dramatically lowers the barrier to entry for building on Ethereum. Whether you're launching a decentralized finance (DeFi) protocol, an NFT marketplace, or integrating wallet connectivity, Infura handles the backend complexity.
Why So Many Projects Depend on Infura
Running a reliable Ethereum node requires significant technical expertise, hardware resources, and continuous maintenance. For startups and independent developers, this overhead can be prohibitive. Infura solves this by offering:
- High availability and scalability
- Low-latency global API access
- Built-in load balancing and failover mechanisms
- Support for both HTTP and WebSocket connections
- Easy integration with popular development frameworks like Web3.js and Ethers.js
Because of these advantages, Infura has become the go-to provider for countless Web3 applications—including MetaMask, which uses Infura as its default Ethereum node provider. That’s why when Infura went down, MetaMask users immediately felt the impact.
The October 2025 Filecoin Expansion: Broadening the Horizon
Infura isn’t limited to Ethereum alone. In October 2025, the platform announced the launch of its Filecoin Network API Beta, enabling developers to connect directly to the Filecoin mainnet and build decentralized storage applications programmatically.
This expansion underscores Infura’s role as a multi-chain infrastructure enabler. By supporting both Ethereum and Filecoin, Infura empowers builders to create applications that combine smart contract logic with secure, decentralized data storage—a powerful combo for next-generation dApps.
Ownership and Evolution: ConsenSys’ Role
Infura was acquired in 2019 by ConsenSys, one of the most influential companies in the Ethereum ecosystem. ConsenSys, founded by Joseph Lubin (a co-founder of Ethereum), develops critical tools like MetaMask, Truffle, and Codefi. Under ConsenSys, Infura has continued to scale, improve reliability, and expand its service offerings.
Despite being a centralized service, Infura plays a vital role in advancing decentralization at the application layer—by allowing more developers to participate in the ecosystem without infrastructure bottlenecks.
The November 2025 Outage: What Went Wrong?
During the recent downtime, Infura stated that they had “provisioned additional processing capacity for affected components” and were analyzing the root cause. While no official post-mortem was immediately released, community speculation pointed toward potential issues with older versions of Geth, the most widely used Ethereum client implementation.
Vitalik Buterin (commonly known as V神) commented in online forums that the Ethereum network itself remained operational—the issue was isolated to specific node providers using outdated Geth versions. This distinction is crucial: the blockchain didn’t fail; the infrastructure layer did.
👉 See how top-tier platforms maintain blockchain reliability during outages
The incident revealed a growing concern: the centralization risks within supposedly decentralized systems. While Ethereum is decentralized at the protocol level, many applications depend on a small number of centralized API providers like Infura. This creates single points of failure that can ripple across the entire ecosystem.
The Exceptions That Prove the Rule
Not all services were affected during the outage. Wallets like Bitcoinist Wallet and Math Wallet, along with exchanges such as Huobi, continued operating normally. Why?
Because they do not rely solely on Infura. These platforms have invested in building their own node infrastructure and API gateways, giving them greater control over uptime and performance.
This resilience highlights an important lesson: true decentralization extends beyond code—it includes infrastructure ownership. As the Web3 ecosystem matures, more projects may follow suit by running their own nodes or diversifying across multiple providers.
Key Takeaways for Developers and Users
- Convenience vs. Control: While third-party providers like Infura accelerate development, overreliance introduces risk.
- Infrastructure Matters: Decentralized apps are only as resilient as their weakest dependency.
- Diversification Is Key: Using multiple node providers or running private nodes enhances reliability.
- Monitoring Tools Help: Real-time health checks and fallback systems can mitigate downtime impact.
Frequently Asked Questions (FAQ)
Q: Is Infura part of the Ethereum network?
A: No. Infura is a third-party service that provides access to the Ethereum network but is not operated by the Ethereum Foundation or core developers.
Q: Can I use Ethereum without Infura?
A: Yes. You can run your own full node or use alternative providers like Alchemy, QuickNode, or Ankr.
Q: Was the Ethereum blockchain down during the outage?
A: No. The blockchain continued processing transactions. The issue was limited to Infura’s API access layer.
Q: Should I stop using MetaMask because it relies on Infura?
A: Not necessarily. MetaMask allows custom RPC configuration, so you can switch to another node provider if needed.
Q: How can developers avoid similar outages?
A: By implementing redundancy—using multiple API providers, running private nodes, or leveraging load balancers across services.
Q: Is Infura centralized?
A: Yes, it operates as a centralized service. However, it supports decentralized applications by reducing infrastructure barriers.
