If you've ever interacted with the Ethereum blockchain through a popular wallet or exchange, you've likely relied on Infura, even if you didn't realize it. In simple terms, Infura is a platform that allows developers, decentralized applications (DApps), and exchanges to quickly connect to the Ethereum network without needing to run their own local node.
On November 11, multiple cryptocurrency exchanges, including Binance, Upbit, and Bithumb, temporarily suspended Ether (ETH) and ERC-20 token deposit and withdrawal services. Users of the MetaMask wallet also reported issues such as incorrect balance displays and data delays. The root cause was soon identified: Infura, a key infrastructure provider, had experienced a service outage affecting its Ethereum Mainnet API.
Understanding Infura and Its Role
Infura is officially classified as an IaaS (Infrastructure as a Service) product. It is a managed cluster of Ethereum nodes that allows developers to deploy smart contracts and access blockchain data without setting up and maintaining their own node infrastructure. This significantly lowers the barrier to entry for building on Ethereum.
How Infura Simplifies Development
As the Ethereum blockchain has grown, the size of a full node has expanded dramatically. Downloading and syncing a full node can take days and may still suffer from occasional synchronization issues. Infura eliminates this hassle by providing reliable, hosted nodes that developers can use via API.
If you've used MetaMask, you've already interacted with Infura—it serves as the default Ethereum provider for the popular wallet. This is why the Infura outage directly impacted MetaMask users.
From a technical perspective, Infura acts as a Web3 Provider. It operates a load-balanced cluster of API nodes, ensuring high availability and reducing the risk of node failure. Beyond Ethereum, Infura also supports interoperability with IPFS (InterPlanetary File System) and has recently introduced beta support for the Filecoin network.
The Recent Service Disruption
The interruption in Infura's Ethereum Mainnet API service on November 11 led to widespread service disruptions across many platforms that depend on it. In response, Infura announced that it was investigating the incident and working to restore functionality. The team later added additional processing capacity to affected components and continued analyzing the root cause of the failure.
Vitalik Buterin, Ethereum's co-founder, commented in a community discussion that the issue might have been related to an older version of the Go Ethereum (geth) client software, emphasizing that the Ethereum network itself remained operational.
The Importance of Decentralized Infrastructure
While many services were affected, some wallets and exchanges continued operating normally. These platforms, such as Huobi exchange and certain non-custodial wallets, did not rely entirely on Infura. Instead, they maintained their own API data services and node infrastructure.
This incident highlights a critical lesson for the blockchain ecosystem: over-reliance on a single service provider, even one as robust as Infura, introduces centralization risks. For the ecosystem to remain resilient, diversification of infrastructure is essential.

Frequently Asked Questions
What is Infura?
Infura is a infrastructure service that provides API access to the Ethereum blockchain, allowing developers to build and run applications without hosting their own nodes.
Why did the Infura outage affect so many services?
Many popular wallets and exchanges use Infura as their default Ethereum node provider. When Infura's API service was interrupted, those platforms lost their connection to the Ethereum network.
Was the Ethereum blockchain itself down during this incident?
No. The Ethereum network continued operating normally. The outage was related to Infura's API service, not the underlying blockchain.
How can developers avoid depending solely on Infura?
Developers can run their own Ethereum nodes or use multiple node providers to distribute risk and increase reliability.
What other services does Infura provide?
In addition to Ethereum, Infura offers access to IPFS and has recently introduced support for the Filecoin network.
Did all wallets and exchanges go down during the Infura outage?
No. Some platforms, including Huobi and certain decentralized wallets, operated normally because they used their own node infrastructure or multiple service providers.
