On October 20, 2025, one of AWS’s largest data centers in Virginia went dark. A DNS failure during a DynamoDB API update cascaded into a massive global outage, crippling over a thousand services - from banking apps to crypto networks like Coinbase, Base, and Infura. It was another reminder that almost everything online, even “decentralized apps,” still runs on someone else’s computer.
AWS had become the beating heart of global infrastructure. So, when it stumbled, the internet staggered. But what truly caught the crypto industry’s attention wasn’t that Coinbase or OpenAI went dark - it was that Ethereum access through Infura also went down.
That led to an uncomfortable question: if blockchain is supposed to be decentralized, why does a bug in one AWS region bring half of Web3 to its knees?
The outage sparked an outpouring of posts on X (Twitter) mocking the “decentralized” facade. Users saw their MetaMask wallets fail to connect, dApps go unresponsive, and exchanges flash blank screens - all because their data highway, Infura, relies on AWS.
As Pocket Network’s Chris Jenkins put it,
Blockchain and the broader internet are only as decentralized as the infrastructure they run on.
The Web3 Paradox: The Consensus Layer vs. The Access Layer
The core machine - the blockchain—is architecturally sound. The Layer-1 (L1) Consensus Mechanism (Proof-of-Work, Proof-of-Stake, etc.) is highly resilient. When AWS failed, global validator sets on networks like Bitcoin and Ethereum continued to process and achieve finality on blocks. The ledger's integrity was never compromised.
The critical disconnect lies in the fact that the average user does not interact directly with the Consensus Layer.
To create a usable product with acceptable latency, the ecosystem has built an intricate, layered dependency stack. This is the Centralized Bottleneck in all its technical glory.
The Achilles' Heel: RPC Provider Concentration
The most glaring SPOF is the reliance on a handful of massive Remote Procedure Call (RPC) providers.
- The Function: An RPC node is the API endpoint that serves as the essential bridge between a user's wallet or dApp and the complex network of L1 nodes. Wallets use these providers for quick read operations (e.g., querying your ETH balance via eth_getBalance) and to broadcast write operations (i.e., sending a signed transaction via eth_sendRawTransaction).
- The Flaw: Major providers like Infura or Alchemy manage vast fleets of nodes, including computationally heavy Archival Nodes, which require massive, stable computational and storage resources. To meet the high demand and maintain low latency, they rely on hyper-scale commercial clouds - predominantly AWS.
- The Outage Mechanism: During the AWS disruption, these providers lost access to crucial cloud components. Consequently, API endpoints failed to resolve or became unresponsive. The wallet did not receive a proper response for the eth_getBalance call, leading to the dreaded zero-balance display. The user was effectively blind, even though their cryptographic keys and funds remained secured on the distributed ledger. This proved that data access, not data immutability, is the current point of failure.
The Unspoken Trade-Off: Efficiency Over Decentralization
Centralization persists because developers prioritize low latency and product performance over protocol purity. Decentralizing every service currently introduces unacceptable friction for a mass-market product.
This necessary compromise creates critical Single Points of Failure (SPOFs) across the stack:
Centralized Bottlenecks Across the Web3 Stack
1. Data Indexing Services (e.g., The Graph)
- Technical Function: Transforms raw blockchain data into queryable GraphQL endpoints for dApp front-ends.
- The Centralized SPOF(single point of failure): Failure in the hosted indexing service means the dApp cannot retrieve and display historical user data or analytics.
2. Front-End Deployment
- Technical Function: Hosting the static assets (UI code) that load the dApp's client experience.
- The Centralized SPOF: Hosting on centralized CDN or S3 buckets makes the dApp vulnerable to both commercial outage and state-level censorship/takedown at the HTTP layer.
3. Oracle Networks (Data Sources)
- Technical Function: Provides authenticated external data feeds (e.g., FX rates) as inputs for smart contract logic (e.g., DeFi liquidation).
- The Centralized SPOF: Reliance on a single, centralized data pipeline introduces data integrity risk and prevents time-sensitive protocol actions if the pipeline fails.
4. Layer-2 (L2) Sequencers
- Technical Function: Entity responsible for ordering off-chain transactions and batching them into a calldata commitment published to the L1.
- The Centralized SPOF: The single sequencer is a temporary SPOF capable of brief transaction censorship or disrupting transaction finality if it goes offline.
The hard truth is that we are currently leveraging the scalable, low-cost compute, storage, and egress bandwidth of Web2 giants to make our "decentralized" applications function acceptably.
The Path Forward: Decoupling the User Experience
The AWS outage was not a technical bug; it was a loud, expensive feature highlighting the fundamental incompatibility between a decentralized core and a centralized periphery. It proves that the job is only half-done.
To truly honor the promise of Web3, the ecosystem must prioritize decoupling the user access layer from its Web2 crutches:
1. Distributed Access Networks: Replacing the concentration risk of single-entity RPC providers with decentralized network protocols (e.g., Pocket Network) that distribute RPC requests across a globally diverse, incentivized pool of independent nodes. This shifts the point of failure from one company's data center to thousands of individual operators.
2. Decentralized Permanent Hosting: Developers must migrate critical front-end assets and static dApp components from centralized CDNs to immutable storage networks (e.g., Arweave, IPFS). This guarantees that the user interface, once deployed, cannot be removed or censored by a governing body or cloud provider failure.
3. Light Client Adoption: We must simplify and promote the use of light client technology and node-as-a-service architecture. This allows users to locally verify the state of the blockchain (achieving data verification) without relying on a full node or trusting a single RPC endpoint for truth
Critics are right to call out the irony, but it’s also worth noting: the blockchains didn’t fail that day. Ethereum, Polygon, and others kept running flawlessly. It’s the layers we built around them—the node providers, cloud bridges, and APIs—that revealed cracks.
That’s the essence of the dilemma: decentralization works, but our access to it doesn’t. Until the pipeline from node to user becomes as resilient as the consensus beneath it, Web3 will continue to live inside a centralized shell.
