Identified
A GA4 (Google Analytics) slowdown caused slow loading and timeouts for CMP organizations using GA4 due to internal dependencies. Our engineering team is rolling out a fix and will update when service is restored.

Update
We have narrowed down the behavior reported in Optimizely Content Marketing Platform (CMP).
Based on our latest findings, CMP is not failing to load. Instead, the first load of the application may take up to approximately 60 seconds to complete, and a loading screen may appear during that time.
We recommend allowing the page to finish loading rather than refreshing as a temporary workaround.
Our Engineering team is continuing to investigate the cause of the delay and to improve load times. We will share more information as soon as we have them at our disposal. We apologize for any inconvenience caused.

Investigating
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.
