After: We are investigating reports that the Optimizely Content Marketing Platform (CMP) is loading slowly or failing to load for some customers. Affected users may see a loading screen that does not finish, or pages that take much longer than usual to open. The issue is intermittent: pages may load, then slow down again when refreshed. Our Engineering team has reproduced the issue and is investigating the cause. We will post an update as soon as we learn more. We apologize for the disruption to your work.
