⚙️ Server Stability Status
During periods of high traffic and of American-based users, our servers may limit data processing to maintain stability for all users. This means that some data may appear partially after synchronization.
🔍 Symptoms You Might Notice
If you experience one or more of the following issues, it may be due to temporary server load management:
-Lack of data granularity — gaps or flat zones in your Activity Intensity graph or missing segments in the Activity Duration pie chart (found under the Energy Circle). -Missing metrics — sleep score, energy level, readiness score, or other related data not showing up after sync. -Lost steps or incomplete activity records.
🧘 What You Can Do
You can synchronize: - Daily. If you have more than 24 hours of data in your ring, it increases the chance of losing data. - During off-peak hours, i.e., not right after you wake up, because everyone synchronizes within a short timeframe.
There’s nothing else you need to do on your side.
🚀 By the End of November 2025
We’re shifting to an architecture where each user gets a dedicated processing calculation instance, so one user’s activity won’t affect another. This upgrade will enable Circular to support millions of users simultaneously with 100% stability for everyone and faster score processing.
Thanks for your patience as we continue improving long-term reliability.
