Continuity steps for Akamai customers
- Document how the site would be served if the edge layer misbehaves: which DNS records change to bypass the proxy, what that exposes, and who can make the change.
- Keep the origin's own TLS certificate valid so that a bypass does not break HTTPS.
- Keep edge configuration (redirects, headers, cache and firewall rules) exported or in version control so it can be rebuilt or moved.
- Rehearse serving from the origin during a quiet period, so you know it can carry traffic without the cache.
