My site suddenly went offline and I can’t even reach the server. No recent edits were made before the outage, and I’m now getting an error page instead of the homepage. I don’t have control-panel access, so you’ll need to work with whatever direct server or DNS credentials I can supply (SSH, SFTP or registrar login). Here’s what I need from you: • Diagnose why the server is unreachable and restore the website to normal operation. (NO DATA LOSS VERY IMPORTANT) • Provide a concise summary of the root cause and any steps I should take to prevent a repeat. If additional configuration on the host’s side is required, please guide me through the exact steps or handle them on my behalf once I give you authorisation. Speed matters—I’d like the site back online today.
