About Cesium
We track Cesium (cesium.com) as part of the Cloud & developer group. The Cesium platform provides the foundations any software application needs to use 3D geospatial data: visualization, data pipelines, curated data, and analytics. Based on open standards for data formats and open APIs for customization and integration—and built with an open source core—Cesium is open, interoperable, and incredibly precise.
Cesium publishes an official status page at status.cesium.com; when we can read it, its incident level is folded into the status shown here.
Common problems for cloud & developer services: API errors, failed deploys or builds, and dashboard or console outages.
Measured uptime from our checks: 100% over 8 days of checks. No public incidents logged since monitoring began 8 days ago.
Response time over the last 24 hours: 107 ms average, 53–221 ms range across 12 successful checks.

Cesium not working for me but the status is fine. What now?
