Why Your Crypto App Stopped Working on October 20: A Beginner’s Guide to Cloud Dependency

If you tried to check your crypto portfolio, make a trade, or use a decentralized app on October 20, 2025, there is a good chance nothing worked. Coinbase had login problems, MetaMask connections failed, and even some blockchain networks slowed to a crawl. The culprit was not a hack, not a blockchain failure, and not a market crash — it was an outage at Amazon Web Services (AWS), the cloud computing giant that powers a surprising amount of the crypto world. Here is what happened, why it matters, and what you can learn from it.

The Basics

Most people think of cryptocurrency as entirely decentralized — that is the whole point, right? No banks, no middlemen, no single point of failure. In theory, that is true. Bitcoin and Ethereum blockchains themselves kept running perfectly on October 20. No blocks were missed, no transactions were lost, and the networks remained secure.

But here is the catch: while the blockchains are decentralized, the services you use to interact with them often are not. The website you visit to check prices, the app you use to trade, the wallet that shows your balance — many of these run on servers owned by Amazon, Google, or Microsoft. When AWS’s US-EAST-1 region experienced a DNS failure starting at around 07:55 UTC on October 20, those services went down too.

Why It Matters

Think of it like a highway system. The roads (the blockchain) are fine, but the on-ramps (the apps and services) are blocked. You cannot get on the highway even though the highway itself is perfectly functional. Research suggests that over one-third of all Ethereum nodes — the computers that verify transactions and maintain the network — are hosted on AWS. When AWS has problems, those nodes go offline, which means fewer on-ramps to the blockchain and slower performance for everyone.

The outage affected Coinbase, Robinhood’s crypto trading, and Base (Coinbase’s Layer-2 network). Decentralized exchanges saw trading volumes drop as price feeds froze. Some users could not access their wallets because the RPC endpoints — the connection points between wallets and blockchains — were running on AWS servers that were down.

Getting Started Guide

So what can you do to protect yourself from the next cloud outage? Here are practical steps every crypto user should take:

Use a hardware wallet. Hardware wallets like Ledger or Trezor store your private keys offline, completely independent of any cloud service. Even if every exchange and every cloud provider goes down simultaneously, your keys remain safe on a physical device in your possession. This is the single most important step for protecting your assets.

Set up multiple RPC endpoints. If you use MetaMask or another browser wallet, you can configure it to connect to different RPC providers instead of relying on a single default. Services like Alchemy, Infura, and public RPC endpoints give you alternatives. If one goes down during an outage, you can switch to another.

Do not keep all your funds on exchanges. The “not your keys, not your crypto” mantra exists for many reasons, and cloud outages are one of them. When Coinbase went down on October 20, users with funds only on the exchange had no way to access or move their assets until the service recovered.

Understand the difference between blockchain and infrastructure. Knowing that a blockchain itself can be perfectly healthy while the services built on top of it struggle is crucial for making informed decisions during crises. Do not panic-sell when you see headlines about crypto outages — the underlying networks are usually fine.

Common Pitfalls

The biggest mistake newcomers make during cloud outages is assuming the blockchain itself is broken. Social media fills with comments about crypto being a failure, but that misunderstands what actually happened. The technology worked as designed; the centralized services built on top of it did not.

Another common pitfall is attempting risky transactions during an outage. When networks are degraded and price feeds are frozen, executing trades or moving large amounts of crypto can result in unfavorable prices or failed transactions. If you can, wait for services to fully recover before transacting.

Finally, avoid falling for scams that emerge during outages. Phishing emails claiming to help you recover access to your account or offering alternative trading platforms spike during these events. Always verify URLs and use only official channels.

Next Steps

The October 20 AWS outage is an opportunity to make your crypto setup more resilient. Start by moving significant holdings to a hardware wallet if you have not already. Configure backup RPC endpoints in your wallet software. Learn how to verify blockchain transactions independently using block explorers like Etherscan, which can function even when some wallet services are down.

The crypto industry is also evolving to address these weaknesses. Decentralized infrastructure networks, often called DePIN, are building alternatives to centralized cloud providers by distributing compute and storage across thousands of independent nodes. As these networks mature, future outages like October 20 should become less impactful — but until then, a little preparation goes a long way.
