Set your domain's nameservers to:

ns1.plume.host
ns2.plume.host

If your domain is registered with Plume Host, nameservers are already correct. Check the My Domains page in your client area.

DNS propagation typically completes within 1–4 hours. We do not believe in the 24–48 hour scare line: real-world propagation is fast on every modern recursive resolver.
