The disruption, which began at 11:25 AM PDT and was resolved by 1:12 PM PDT, was traced not to a cyberattack or internal technical failure, but to a server block imposed by GoDaddy Registry the manager of the .us top-level domain after a communication mishap with Zoom’s domain registrar, Markmonitor. GoDaddy Registry, responsible for the .us namespace, mistakenly shut down the zoom.us domain after a flawed exchange with Markmonitor, Zoom’s domain management provider. A registry lock has been placed on the zoom.us domain, restricting server block commands and adding another layer of manual confirmation for any future changes. While the absence of a security breach is reassuring, the fact that a single miscommunication could take down a platform as essential as Zoom underscores the need for heightened vigilance and redundancy in domain management. The outage left users in the US and internationally unable to access Zoom services, including meetings, phone calls, and even Zoom’s own status page. Zoom’s investigation revealed that its own domain name servers were functioning correctly, but DNS resolution for the zoom.us domain was failing at the top-level domain (TLD) level. On April 16, 2025, millions of users worldwide found themselves unable to access Zoom, the widely used video conferencing platform, due to a critical outage that lasted nearly two hours. As businesses and individuals increasingly rely on cloud-based collaboration tools, the Zoom outage serves as a stark reminder: the resilience of digital services is only as strong as the weakest link in their supply chain. Once the issue was identified, Zoom, Markmonitor, and GoDaddy collaborated to remove the server block.
