Zoom Outage History

A subset of Zoom customers experienced degraded Live Transcription and Voice Recognition services starting Apr 21, 2025 12:44 PM UTC. The impact touched Zoom Meetings / Live Transcription and the Zoom Virtual Agent, with intermittent problems reported across AIC service, live transcription, and voice recognition. The outage lasted about 50 minutes, with services returning to normal by Apr 21, 2025 1:34 PM UTC.

Zoom’s status page documented the incident progression across three updates: an initial investigation at Apr 21, 2025 12:44 PM UTC, followed by an identification of issues affecting AIC service, live transcription, voice recognition, and ZVA at Apr 21, 2025 1:29 PM UTC, and finally a resolution indicating the affected components were restored by Apr 21, 2025 1:34 PM UTC. This was a brief partial outage with limited scope rather than a global service disruption.

A partial outage impacted the compose and chat summary features of Zoom Team Chat using AI Companion for a subset of users. The incident began on 4:04 AM UTC with Zoom reporting an investigation into an issue affecting the Zoom Chat / Zoom AIC component, and was resolved by 5:44 AM UTC. The outage lasted approximately 1 hour 40 minutes, and Zoom issued 2 status updates during the incident.

A DNS/domain name resolution problem on the zoom.us domain began around Apr 16, 2025 7:19 PM UTC and impacted multiple Zoom services, including Zoom Meetings, Zoom Website, Zoom Phone (Admin/Users/Provisioning/Dashboard & Reporting), and the Zoom Contact Center Web Portal. Users reported login failures, difficulty joining or starting meetings, and intermittent connectivity issues, with a notable surge in reports during the evening. Zoom issued status updates acknowledging the domain resolution issue and later provided remediation guidance related to DNS caches. The outage lasted roughly 5 hours and 15 minutes, with services gradually restoring and all affected components returning to normal by Apr 17, 2025 12:34 AM UTC.

Zoom carried out a scheduled maintenance window affecting three components: Zoom Phone - Global / Web Portal (Admin/Users/Provisioning/Dashboard & Reporting), Zoom Workforce Management, and Zoom Phone - Global / Zoom Phone. The maintenance began at Apr 13, 2025 12:04 AM UTC and ended at Apr 13, 2025 9:04 AM UTC, with Zoom indicating no operational impact on services during this period. No user reports were observed during the window.

During the incident, Zoom issued two official status updates to communicate the maintenance and subsequent restoration of all components by Apr 13, 2025 9:04 AM UTC.

This was a planned maintenance window impacting Zoom Phone in APAC and related Zoom services. The work began at Apr 11, 2025 2:34 PM UTC and concluded at Apr 12, 2025 9:04 AM UTC, lasting about 18 hours and 30 minutes. Affected components included Zoom Phone - APAC, Zoom Virtual Agent, and Zoom Contact Center (Global Web Portal Admin/Users/Provisioning and Zoom Contact Center). The provider issued four status updates during the incident, indicating ongoing maintenance and progression toward completion. All affected components returned to normal operation by Apr 12, 2025 9:04 AM UTC.

Zoom experienced two related issues: user presence status not updating when using Zoom Interop for Microsoft Teams, and connectivity problems with international dial-in numbers from Japan affecting a subset of users. The outage began at 2:34 AM UTC and impacted two components: Zoom Chat / User Profiles and Presence and Zoom Meetings / Meeting Dial-in/Telephony. The disruption caused stale presence information and dial-in failures for some meetings, lasting about 6 hours and 35 minutes and with service returning to normal by 9:09 AM UTC.

The provider issued four status updates documenting the investigation, the Japan-specific dial-in impact, a fix, and monitoring for full recovery. Geographic impact was focused on Japan for the dial-in issue, while presence-related issues were observed in the affected features as updates progressed; by the end of the incident the affected components had recovered and Zoom was reported as fully available.

Zoom presence interop with Microsoft Teams caused a brief disruption where Zoom presence status did not update in Microsoft tools for users with presence interop enabled. This affected Zoom Chat / User Profiles and Presence, potentially leaving teams with stale presence information for a few hours and impacting collaboration workflows. The outage began at Apr 8, 2025 7:04 PM UTC and was resolved by Apr 8, 2025 10:54 PM UTC, lasting approximately 3 hours and 50 minutes. The Zoom status page published 2 updates during the incident while teams monitored the situation.

Zoom conducted scheduled maintenance for the Hyderabad Datacenter, affecting Zoom Phone services in the APAC region. The maintenance began at 11:34 AM UTC and ended at 11:49 PM UTC, lasting about 12 hours and 15 minutes. The affected component was Zoom Phone - APAC / Zoom Phone.

During the window, the status page indicated the maintenance was in progress with updates provided as necessary. The APAC Zoom Phone service returned to normal after the maintenance window, with updates posted to reflect the progression from maintenance back to normal operation.

Zoom Rooms experienced degraded connectivity affecting a subset of users. The incident began at 6:09 AM UTC and lasted for about 1 hour and 25 minutes, with some users unable to join or maintain Zoom Rooms meetings during the window. The issue was isolated to Zoom Rooms and did not indicate a broader disruption across Zoom services.

The service team published two official updates during the incident: the initial notification that an investigation was underway and degraded connectivity, followed by an update confirming the issue had been resolved and Zoom Rooms returned to normal by 7:34 AM UTC.

Zoom experienced a short-lived degradation impacting Zoom Rooms, Zoom Mail/Calendar, and Zoom Workspace Reservation. The issue began at 5:24 PM UTC and, after Zoom identified the problem, the affected components returned to normal by 5:59 PM UTC. The Zoom status page indicated the issue and provided updates as the investigation progressed, with services resuming normal operation shortly after the incident. The degradation primarily affected scheduling, conferencing room management, and calendar workflows across Zoom Rooms environments.
