GoDaddy Registry Error Knocked Zoom Offline for Nearly Two Hours

A communication error between GoDaddy Registry and Markmonitor took Zoom's services offline for almost two hours on Wednesday when GoDaddy mistakenly blocked the zoom.us domain. The outage affected all services dependent on the zoom.us domain. GoDaddy's block prevented top-level domain nameservers from maintaining proper DNS records for zoom.us. This created a classic domain resolution failure -- when users attempted to connect to any zoom.us address, their requests couldn't be routed to Zoom's servers because the domain effectively disappeared from the internet's addressing system. Video meetings abruptly terminated mid-session with browser errors indicating the domain couldn't be found. Zoom's status page (status.zoom.us) went offline, hampering communication efforts. Even Zoom's main website at zoom.com failed as the content delivery network couldn't reach backend services hosted on zoom.us servers. Customer support capabilities collapsed when account managers using Zoom's VoIP phones lost connectivity. Resolution required coordinated effort between Zoom, Markmonitor, and GoDaddy to identify and remove the block. After service restoration, users needed to manually flush their DNS caches using command line instructions (including the sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder command for Mac users).
