-## Use Cloudflare Cache features to optimize caching
-
-By default, Cloudflare [caches static content](/cache/concepts/default-cache-behavior/) such as images, CSS, and JavaScript. However, you can extend Cloudflare caching to work with HTML by creating custom [Cache Rules](/cache/how-to/cache-rules/).
-
-### Cache more requests
-
-1. In the Cloudflare dashboard, go to the **Account home** page and select your account and domain.
-
-    <DashButton url="/?to=/:account/home" />
-
-2. Go to **Caching** > **Cache Rules** and select **Create rule**.
-
-3. For **When incoming requests match**, enter either your entire website or a specific path on your application, based on the **Hostname** or **URI Path**. Refer to the [available fields](/cache/how-to/cache-rules/settings/#fields).
-
-4. For **Cache eligibility**, define how these requests should be cached and for how long. Refer to the available [cache eligibility settings](/cache/how-to/cache-rules/settings/#eligible-for-cache-settings).
-
-5. You can then monitor the effectiveness of your cache settings using [Cache Analytics](/cache/performance-review/cache-analytics/) and update your configuration according to our [Cache performance guide](/cache/performance-review/cache-performance/).
-
-### Advanced cache optimizations
-
-* [Custom Cache Keys](/cache/how-to/cache-keys/) allows you to precisely set the cacheability setting for any resource.
-
-* [Origin Cache Control](/cache/concepts/cache-control/) can be used to let the `Cache-Control` headers tell Cloudflare how to handle content from the origin server.
-
-### Use Tiered Cache
-
-[Tiered Cache](/cache/how-to/tiered-cache/) uses the size of Cloudflare's network to reduce requests to customer origin servers by dramatically increasing cache hit ratios.
-
-It works by dividing Cloudflare's data centers into a hierarchy of lower-tiers and upper-tiers. If content is not cached in lower-tier data centers (generally the ones closest to a visitor), the lower-tier requests an upper-tier for the content. If the upper-tier does not have the content, only the upper-tier will initiate a request to the origin. This practice improves bandwidth efficiency by limiting the number of Cloudflare data centers that can ask the origin for content.
-
-Refer to [Enable Tiered Cache](/cache/how-to/tiered-cache/#enable-tiered-cache) to get started.
-
-### Use Cache Reserve
-
-[Cache Reserve](/cache/advanced-configuration/cache-reserve/) is a large, persistent data store implemented on top of [R2](/r2/).
-
-With a single click in the dashboard, your cacheable content will be written to Cache Reserve. In the same way that Tiered Cache builds a hierarchy of caches between your visitors and your origin, Cache Reserve serves as the ultimate [upper-tier cache](/cache/how-to/tiered-cache/) that will reserve storage space for your assets for as long as you want.
-
-This ensures that your content is served from cache longer, shielding your origin from unneeded egress fees.
-
-## Understand the limits of your hosting plan
-
-Cloudflare offsets most of the load to your website via caching and request filtering, but some traffic will still pass through to your origin. Knowing the limits of your hosting plan can help prevent a bottleneck from your host. 
-
-Once you are aware of your plan limits, you can use [Rate Limiting](/waf/rate-limiting-rules/) to restrict how many times a requesting entity can make a request to your website.
-
-To help you define the best rate limiting setting for your use case, refer to [How Cloudflare determines the request rate article](/waf/rate-limiting-rules/request-rate/).
-
-## Cloudflare Waiting Room
-
-[Cloudflare Waiting Room](/waiting-room/) allows you to route excess users of your website to a customized waiting room, helping preserve customer experience and protect origin servers from being overwhelmed with requests.
-
-## Use Cloudflare IP addresses to your advantage
-
-Take action to prevent attacks to your application during peak season by configuring your firewall to only accept traffic from Cloudflare IP addresses. By only allowing [Cloudflare IPs](https://www.cloudflare.com/ips), you can prevent attackers from bypassing Cloudflare and sending requests directly to your origin.
-
-Refer to [Cloudflare IP addresses](/fundamentals/concepts/cloudflare-ip-addresses/) for more information.
-
-## Monitor traffic in your Cloudflare dashboard
-
-You can use the Cloudflare dashboard to closely monitor the traffic on your domain and fine-tune your cache and security settings accordingly.
-
-### Zone and Account analytics
-
-[Cloudflare zone analytics](/analytics/account-and-zone-analytics/zone-analytics/) gives you access to a wide range of metrics, collected at the website or domain level.
-
-[Cloudflare account analytics](/analytics/account-and-zone-analytics/account-analytics/) lets you access a wide range of aggregated metrics from all the sites under a specific Cloudflare account.
-
-### Security Analytics and Security Events
-
-[Security Analytics](/waf/analytics/security-analytics/) displays information about all incoming HTTP requests for your domain, including requests not handled by Cloudflare security products.
-
-You can also use the [Security Events](/waf/analytics/security-events/) to review mitigated requests and tailor your security configurations.
-
-### Cache Analytics
-
-You can use [Cache Analytics](/cache/performance-review/cache-analytics/) to improve site performance or reduce origin web server traffic.
-Cache Analytics helps determine if resources are missing from cache, expired, or ineligible for caching.

+We encourage you to customize every page to provide a consistent branding experience for your users. Origin Error pages can also be activated for 502, 504, and 404 errors.

+Reach out to your Customer Success Manager at least 30 days prior to the expected traffic surge to schedule a Security Optimization walkthrough with your Customer Solution Engineer.
+
+To learn more about our service offerings, refer to [Customer Success offerings](https://www.cloudflare.com/success-offerings/).
+
+## Register your users
+
+For the security and protection of your account, be sure to register all account users.
+
+1. In the Cloudflare dashboard, go to the  **Manage Account** > **Members** page.
+
+    <DashButton url="/?to=/:account/members" />
+
+2. Select more than one Super Administrator to ensure appropriate access when needed.
+
+:::note
+
+Refer to [Manage members](/fundamentals/manage-members/) to learn how to review and update registered account users. 
+
+:::
+
+Failure to register account users can create issues with our ticketing system. Unverified users who contact support will be funneled to the self-serve queue rather than the Enterprise queue which can result in long wait times.
+
+We strongly advise against credential-sharing which can jeopardize the trust and safety of your account.
+
+## Confirm user and domain administration
+
+- **Multi-User:** Provide role-based permissions to a group of users to better control the administration of your domains. Each user has their own role and limited API key.
+- **Enforce 2FA:** Ensure your entire dashboard is secure by [enforcing 2-factor authentication](/fundamentals/user-profiles/2fa/) for your organization.
+  - To disable 2FA, submit a support ticket and allow 1-2 business days to validate your request.
+- **Leverage API Access:** Work easily with our system programmatically using our [API](https://api.cloudflare.com).
+
+## Additional items
+
+- Check when your [SSL Certificates expire (only custom and origin certificates)](/ssl/edge-certificates/custom-certificates/renewing/)
+  :::note
+  Certificates managed by Cloudflare are auto-renewed.
+  :::
+- Review your Operational and Disaster recovery preparedness
+    - Enable Load Balancing with smart cache strategies: Use [Cloudflare Load Balancing](/reference-architecture/architectures/load-balancing) to distribute traffic across multiple healthy origins, and increase cache-hit ratios by leveraging [custom cache rules](/cache/performance-review/cache-analytics) and [edge compute](https://www.cloudflare.com/learning/cdn/caching-static-and-dynamic-content/) (e.g., Cloudflare Workers) to offload origin traffic during high-demand periods.
+    - Configure failover pools and back up DNS with a playbook: Set up [Cloudflare Load Balancer failover pools](/reference-architecture/architectures/load-balancing) to automatically redirect traffic to healthy origins if one fails. Export DNS records for safekeeping and prepare a clear [incident response plan](https://www.cloudflare.com/learning/performance/preventing-downtime) that includes steps for re-routing or recovery.
+- Review and update your current users' access
+- Check your domain registry validity
