// What happened

Zoom's official status page is reporting a minor Partially Degraded Service, though Downrightnow's signals are currently mixed with quiet user reports and normal DNS resolution. Zoom has also scheduled network maintenance for its Amsterdam and Frankfurt data centers beginning May 21, 2026, which may affect a wide range of components including Zoom Meetings, Phone, and webinars. Because automated signals are stable and recent reports are low, any current impact appears isolated rather than a broad outage.
