On October 27, 2026, at 12:36 UTC, some customers in our US1 region experienced timeouts when logging in to Anaplan or opening their workspaces. **Root cause** The login disruption was caused by an automated safety filter that our content delivery network \(CDN\) provider activated to manage a sudden spike in internet traffic. The traffic spike subsided within two minutes, but the safety filter remained active and mistakenly blocked legitimate customer connections. This happened because secure connection messages sent by modern web browsers, after passing through standard corporate network security firewalls, matched the specific traffic characteristics that the safety filter was trying to block. The issue lasted for a few hours because blocked browsers kept automatically trying to reconnect, which kept the automated filter active. Anaplan's applications, login services, and internal systems worked normally throughout the event. **Recovery** Our engineering team investigated as soon as customers reported the issue and linked it to a known third-party issue that our CDN provider had reported. We worked with the CDN provider while they put a fix in place, and affected customers had normal access again by 15:03 UTC. We didn't need to change any Anaplan infrastructure or configuration. **Corrective and preventative actions** * The vendor is refining automated mitigation rules to target specific network locations by default, which will reduce the scope of any potential impact. * Cloudflare is enhancing its traffic fingerprint analysis to better differentiate between malicious activity and legitimate modern browser connection patterns. We apologize for the impact this issue has had on your operations. We're committed to the improvements outlined above to prevent similar disruptions. If you have questions or concerns, please contact Support. --- [2026-10-27T15:41:38.415Z] (resolved) We have confirmed that the issue is now resolved.

On October 26, 2026, at 10:47 UTC, we became aware of an issue which affected our me1: Cloud - Saudi Arabia region. As a result of this issue, customers experienced difficulties accessing the Home and Models pages. While the main navigation pages were unavailable, users could sign in and access models via direct or bookmarked links, or through user experience \(UX\) application pages.  **Root cause**  During a planned routing configuration update during the scheduled downtime window on October 24th, an incorrect configuration setting was left in place on the application routing configuration for the me1 region. This configuration was not successfully updated during the maintenance window, causing subsequent attempts to navigate to the Home and Models pages to return error responses.  **Recovery**  Our engineering team took immediate action upon becoming aware of the issue. We paused automated deployment synchronization and manually updated the routing configuration to remove the incorrect setting. Access was restored at 10:58 UTC. The permanent automated configuration update was completed at 11:18 UTC, and the issue was fully resolved.  **Corrective and preventative actions**  * We are updating our migration validation procedures to verify the active running configuration across all environments and regions.  * We are updating our alerting configurations to guarantee that any failures persisting beyond the planned downtime correctly trigger active alerts as soon as the maintenance window is completed.  * We are strengthening our automated smoke testing framework to prevent configuration gaps from going unnoticed.  We apologize for any impact this issue may have had on your business operations.` `We are continuously strengthening our systems and procedures to ensure we avoid future disruptions to your business and users.  If you have further questions or concerns, please visit our [Support](http://support.anaplan.com) website.

Users are unable to navigate to models via the Anaplan UI. Impact: - Model navigation via UI: Affected — users are unable to browse to or open models through the standard UI navigation. - Model access via shortcut links: Available — users who have a direct shortcut or bookmarked link to a model can still access it. - Already active sessions: Unaffected — users currently logged into a model are not impacted. - Apps: Unaffected. We are working to identify the root cause and restore full navigation as quickly as possible. We will provide an update in 30 minutes or as soon as we have more information.

Important: IP allowlist update Anaplan is expanding its network to boost platform performance and support long-term growth. We’re adding new IP addresses to the active production environment for in1: Cloud - India on November 16, 2026. If you’re using this region and you restrict inbound traffic and have allowlisted Anaplan IP addresses, you'll need to update your firewall settings. The action is straightforward: you must add the new Anaplan IP addresses to your existing allowlists without removing the current ones. Both IP ranges will stay active. You’ll find the complete, up-to-date list in the “URL, IP, and allowlist requirements” article on our Support website. You can use our onsite search to find the article, or you can copy/paste this URL into your browser: https://support.anaplan.com/url-ip-and-allowlist-requirements-c8235c7d-8af2-413b-a9ff-d465978806b9. If you don't update your firewall settings before November 16, 2026, you risk connectivity failures that could affect key platform components, including Anaplan CloudWorks™ and Anaplan Data Orchestrator (ADO). To prevent any service disruptions, we strongly recommend coordinating with your internal IT or network security teams as soon as possible so that they can apply the necessary updates. If you need additional help, please contact your CSBP or Anaplan Support.
