What happened
Cloudflare's Certificate Transparency Monitoring is now generally available after being in beta since 2019, covering over 650,000 domains. The GA release fixes a major noise problem by filtering out alerts for certificates Cloudflare issues and renews on your behalf, so you only get notified about unexpected external certificates.
Why it matters
If you previously disabled CT Monitoring because of spam from routine Cloudflare certificate renewals, you should re-enable it now; the GA version only alerts you to certificates issued outside Cloudflare, which is critical as certificate lifespans shrink to 47 days by 2029 and renewal frequency increases.
Discussion angle
How the shrinking certificate lifespan (down to 47 days by 2029) will force more automation and better alert filtering across all infrastructure tools, not just Cloudflare.
