Apple's verification servers experienced a three-hour outage on Tuesday afternoon, preventing developers from installing and testing enterprise-signed apps. The disruption occurred between 3 PM and 6 PM Eastern Time on March 10, 2026, affecting developers worldwide who rely on these servers for app signing and verification processes.

To test applications compiled through Xcode, developers must have their apps signed through Apple's verification servers. These servers are essential not only for enterprise applications but also for local app installations. During the outage, developers reported being unable to verify applications and instead received error messages stating that an Internet connection was required to verify trust of the developer.

The outage is sure to have disrupted and slowed down the workflows of countless developers and development teams, as no one was able to test updated builds of applications. Developers of enterprise apps claim that no new installs were possible for a while, but Apple has since resolved the matter. The single point of failure is a problem that Apple should address in the future.
