In the history of the internet, perfect uptime is almost mythical. DNS servers fail, CDNs crash, and even Bitcoin sits at 99.98% uptime since 2009. But Ethereum? Not once. Not ever.
Since July 30, 2015, Ethereum has maintained an unbroken record of 100% uptime. This is unprecedented for a system of its complexity and scale.
The Promise of True Ownership
Traditional systems fail you when you need them most. When your bank goes down, your money becomes inaccessible. When payment processors crash, commerce stops. When exchanges halt trading, you're locked out of markets. You own nothing but promises from institutions that can break them at any moment.
Ethereum solves this. Here, your assets live on an unstoppable network that has never failed. Your smart contracts execute exactly as programmed, every time. Your DeFi positions remain accessible 24/7, regardless of corporate decisions or system maintenance windows.
While legacy systems trap your assets behind gates that can slam shut, Ethereum has kept those gates open for nearly a decade straight. That's the difference between conditional access and true ownership.
Building the Impossible
Perfect uptime isn't luck. It's extraordinary engineering. Ethereum has maintained this record while executing the most complex operations in computing: processing smart contracts, managing state across thousands of nodes, and surviving "The Merge" without missing a beat.
Client diversity has saved Ethereum from downtime due to client bugs multiple times. Ethereum's diversity is unmatched, with 6 consensus clients and 6 execution clients built around executable Python specs. Learn more at clientdiversity.org.
This is a decentralized system with no central control, no emergency shutdown, and no admin to restart it when things break. Yet it has consistently outperformed many centralized alternatives.
The Foundation of Trust
When developers build apps, users deposit savings, and institutions integrate with Ethereum, they're betting on one promise: the network will always be there, forever. This long-term perspective matters. Traditional institutions that seemed permanent for decades (like Lehman Brothers or Bear Stearns) can disappear overnight. Ethereum is built to endure.
Setting a New Standard
Ethereum sits alone among complex internet systems to achieve true 100% availability over nearly a decade. While traditional systems boast "five nines" (99.999%), Ethereum will continue to deliver perfect, unbroken service. Forever.
This proves decentralized systems can exceed centralized reliability. In a world where critical systems occasionally fail, Ethereum's 100% uptime stands apart. Zero downtime isn't an accident. It's careful engineering and a network design so robust it has never failed, never faltered, and never stopped.
That's not just uptime. That's what perfect infrastructure looks like.
