How long does it take for a new subdomain to become active?

After creating a new subdomain in cPanel, it typically becomes active within a few minutes. However, it can take up to 24 hours for DNS propagation to complete across the internet, depending on your hosting provider and DNS configuration. This delay is due to the time required for domain name servers around the world to recognize the new subdomain. During this propagation period, your subdomain may not be accessible to everyone immediately, but it will gradually become available worldwide as the changes propagate.
