I created the DevOps Emergency

I created the DevOps Emergency Toolkit as a practical resource for DevOps engineers, system administrators, and IT professionals who need to troubleshoot production infrastructure quickly and safely. It covers Linux server diagnostics, Docker and container troubleshooting, Nginx, SSL/TLS, DNS and networking, systemd and logs, incident response, security-aware recovery, and server hardening. The toolkit includes ready-to-use commands, troubleshooting workflows, checklists, decision trees, and incident handoff and postmortem templates designed for real-world operational scenarios
