When your website stops responding, the first task is to establish what is affected and give the right person useful information. Avoid changing several settings at once: that can make the original problem harder to identify.
Check what visitors see
Open the site on another device or network and try a private browser window. Ask someone else to check too. Note whether the whole site is unavailable or only a page, form or login. Copy the exact error message, the affected address and the time. A screenshot can help.
A 500 error indicates a server-side problem, but does not identify its cause. A browser warning about a certificate, a domain that does not resolve, and a page that loads but fails to submit a form need different investigations.
Find the right contact
Check your hosting provider's status page for a known incident. If the domain has expired or its DNS settings have changed, involve the person responsible for the domain. If the server reports an error after a site update, contact the developer or maintainer and tell them what changed. For a certificate warning, contact the person managing hosting or HTTPS.
If you suspect a compromise, such as unfamiliar redirects or content, contact the person responsible for security. Avoid entering credentials on a suspicious page. Preserve relevant evidence and coordinate recovery with your provider or specialist.
Recover carefully
Confirm that a usable backup exists before making changes. A restore may overwrite recent orders, submissions or other data, so agree on what will be lost and how it will be recovered. Avoid guessing at DNS settings, deleting files or repeatedly restoring backups. Once repaired, test important journeys such as contact forms and checkout, not just the homepage.
Reduce the impact next time
Keep an accessible record of the domain, hosting and maintenance contacts. Check renewals, maintain and test backups, and monitor availability so the right people can respond sooner. Monitoring can tell you there is a problem; it does not replace a recovery plan.
