On May 5, 2026, DENIC published broken DNSSEC signatures for the .de TLD, making millions of domains unreachable. Here's what 1.1.1.1 saw, how serve stale cushioned the impact, and how we restored resolution. https://blog.cloudflare.com/de-tld-outage-dnssec/

Born in Canada, engineered for global impact. We are incredibly proud of our Co-founder, and President Michelle Zatlyn for being recognized among the 2026 #GreatImmigrants.
Thank you, Michelle, for your dedication to innovation and a #BetterInternet! https://carnegie.org/great-immigrants/michelle-zatlyn/

When a broken DNSSEC rollover took down the .AL top-level domain, we deployed a Negative Trust Anchor on 1.1.1.1 to keep sites reachable. Now, clients do not have to guess if validation was skipped: 1.1.1.1 returns EDE 33, a new error code signaling that validation was temporarily skipped. https://blog.cloudflare.com/dnssec-nta-ede-33/

Cloudflare Research is building a global consensus service called Meerkat that uses a new consensus algorithm called QuePaxa. We plan to use Meerkat to build a strongly consistent, fault-tolerant key-value store, and other applications. https://blog.cloudflare.com/meerkat-introduction/

Cloudforce One conducted research into how linguistic deception and file structure can be used to bypass AI-driven code auditors across 18,400 API calls. The findings show that malicious detection rates drop when deceptive comments make up less than 1% of a file and that burying payloads in files larger than 3MB effectively blinds models to malicious intent.
