Complaint: “Cannot open on Mobile.” SpeedCE Mobile filter mostly red; Telecom and Unicom green. Diagnosis: Mobile routing not optimized—not a full-site outage. Targeted CDN Mobile tuning instead of blind server scale-up.

Lessons Learned
Real outages are often regional, protocol-specific, or time-dependent—a single local test easily misleads. SpeedCE uses distributed nodes and map visualization to mirror real user experience and move troubleshooting from guesswork to evidence.
