postmortem
On **June 18, 2025**, the **Cookiebot Consent Management Platform \(CMP\)** experienced a significant service disruption that affected websites using the **EU CDN feature** for the Consent Banner.
The incident resulted in three key issues:
* **Consent Banner Rendering Failure**: Consent banners were not displayed on impacted websites, limiting users’ ability to review or provide consent — potentially affecting transparency and compliance.
* **Consent Ingestion Issues**: User consent data was not reliably captured or processed during the affected period, which may have implications for regulatory compliance depending on configuration.
* **Blocking Script Behavior**: The CMP script exhibited blocking behavior in some cases, which may have negatively impacted page load performance and interfered with other client-side scripts.
**Impact Scope:**
This incident **only affected Cookiebot Consent Banners utilizing the EU CDN option**. Other configurations were not impacted.
**Timeline:**
The issue began at **10:00 AM UTC** and was resolved by **4:45 PM UTC**, lasting approximately **6 hours and 45 minutes**.
