Summary: On May 5, 2026, between 04:48 PM and 07:54 PM EDT, users may have experienced difficulties accessing app.become1.de due to a global issue affecting the .DE Top-Level Domain (TLD).
Impact: During this window, DNS queries for our domain returned SERVFAIL errors for many users, specifically those using security-aware DNS providers (like Google or Cloudflare). This resulted in the application being unreachable, although our internal servers and data remained fully operational and secure.
Root Cause: The issue was identified as an upstream failure at the .DE Registry (DENIC). Following a scheduled maintenance window, the registry encountered a global DNSSEC signing error. This caused external DNS resolvers to reject records for .DE domains as a security precaution.
