During the process, a domain configuration conflict occurred, rendering the Knowledge Base and Support Portal inaccessible to users. To ensure immediate service availability, the team performed a full rollback to the original environment. After resolving a technical delay in domain validation (CNAME generation) the connection was successfully re-established.

Instability in ASM scantargets https://status.zanshin.tenchisecurity.com/incident/769096 Tue, 18 Nov 2025 13:20:00 -0000 https://status.zanshin.tenchisecurity.com/incident/769096#92f12ecfcb440c78a0d303d1bb49c65be540f94840f3135a216c9974fa67b523 The problem was identified: one of the data sources we use, Security Trails, experienced internal issues that removed our payment methods and blocked all calls to its API, drastically reducing the data sources in our ASM scans. Unfortunately, their support took approximately 16 hours to respond to the support request and 18 hours to get them back up and running. We also noticed issues with other accounts we use for testing, research, and even creating new accounts. At the time of this update, the Security Trails status page had not yet been updated. The API is now responding again. We are running the problematic scans again and adding other domain and subdomain data sources to improve the robustness of our scans.
