On November 20, 2025, Dominic Williams, founder of the Internet Computer (ICP) protocol developed by DFINITY, announced a significant step toward greater decentralization. The move comes in direct response to a major Cloudflare outage just days earlier, which disrupted access to numerous websites and applications worldwide.
The Cloudflare disruption, which occurred around November 18, 2025, stemmed from an internal issue (reportedly related to database permissions affecting its bot management system), causing widespread 500 errors and downtime for services relying on Cloudflare’s infrastructure—including DNS resolution for many domains. While traditional web services and even some crypto platforms experienced interruptions, applications hosted natively and fully on-chain via the Internet Computer continued to function without issue.
As Williams explained in his post:
“When Cloudflare went down, apps onchain on the Internet Computer continued running, however… some users experienced issues where apps used Cloudflare for DNS (domain names). So, decision made, we’re going to bring that onchain too (DNSSEC + NNS + chain key).”
This highlights a key vulnerability: even when backend logic and content reside on a decentralized network like ICP, users may still fail to reach those services if domain name resolution depends on centralized providers like Cloudflare.
To eliminate this last point of centralization and single-point-of-failure risk, the plan involves integrating DNS (Domain Name System) functionality directly onto the Internet Computer blockchain. The approach will leverage:
- DNSSEC for secure authentication of DNS data,
- The NNS (Network Nervous System, ICP’s decentralized governance DAO),
- Chain Key cryptography (a core ICP innovation enabling threshold signatures, secure multi-chain interactions, and tamper-proof operations).
By bringing DNS on-chain, ICP aims to make domain resolution resilient to outages from any single provider, further advancing the protocol’s vision of a fully decentralized “world computer” capable of hosting tamperproof, unstoppable online services end-to-end.
The announcement quickly gained traction in the ICP community, with replies praising it as a major resilience upgrade. One user noted: “Bringing DNS on-chain closes another gap and makes the whole ecosystem more resilient… during the next Cloudflare outage, we’ll actually see all ICP websites stay online.”
This development underscores ICP’s ongoing push to replace centralized internet dependencies with blockchain-native alternatives, positioning it as a potential alternative to traditional cloud and infrastructure providers.
