"This site can't be reached" usually means DNS hasn't propagated yet (can take up to 24-48 hours after a change) or the domain has expired. "Domain parked" means the domain is registered but not yet pointed to a hosting server. If your website was working and suddenly stopped, check your domain's expiry date and DNS records first — these are the two most common causes. You can check DNS status anytime from your Customer Dashboard, or reach out via Live Chat and we'll investigate immediately.
