Title: GoDaddy Registry Error Knocked Zoom Offline for Nearly Two Hours

Link: https://it.slashdot.org/story/25/04/18/112324...

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).
