8 Regions: Seoul, Tokyo, Sydney, Singapore, Frankfurt, Virginia, Oregon, London

Simulate real global user access speeds through 8 regions distributed across major internet hubs worldwide (Asia, North America, Europe, Oceania).

• Asia (Seoul, Tokyo, Singapore) → Covers East & Southeast Asia
• Oceania (Sydney) → Australia and Pacific region
• North America (Virginia, Oregon) → East & West coast hubs
• Europe (Frankfurt, London) → Western & Central European major hubs

These 8 regions are core hubs commonly operated by global infrastructure providers like Cloudflare, AWS, and GCP, representing the majority of worldwide internet traffic.

Web-PSQC sends API requests to self-built testing servers in each region, aggregates all results, and generates reports.
This process takes approximately 30 seconds to 2 minutes.
