// User impact

Zoom users likely saw failed connections, degraded availability, or session instability for this Productivity service. The incident reached Minor severity and lasted 6h 4m. The stored report window does not show a preserved user-report spike.

// What happened

Zoom’s official status page lists scheduled network maintenance in the AMS datacenter (5/19–5/21) and the Frankfurt data center (May 19–21), covering components including Zoom Meetings, Zoom Phone, Zoom Rooms, Zoom Webinars, Cloud Recording/Recording, and Meeting Dial-in/Telephony. Downrightnow’s current signals are mixed but lean quiet: DNS is resolving normally, user reports and Hacker News chatter are calm, and there’s no major regional network anomaly, so any impact may be limited or intermittent rather than a broad Zoom outage. Zoom Status also noted: “Zoom Phone and Zoom Contact Center are experiencing intermittent degradation affecting MMS delivery in the United States and Canada regions,” which may be related if you’re seeing messaging issues there.
