Why does Cloudflare still show my old nameservers after I updated them?
When you update your nameservers, it can take 24–48 hours (sometimes up to 72 hours) for the changes to fully update across the internet (DNS propagation). Until then, some systems may still display your old nameservers.
If it’s been more than 48 hours and Cloudflare still shows the old nameservers, please double-check with your registrar that the Cloudflare nameservers were entered correctly.
