FAQ
Why are servers fast at peak hours? How does the Mainland China–Hong Kong dedicated line keep service stable? 
Many people ask whether a VPN gets slow or flaky during evening peak hours. For users in Mainland China, our design relies on contracted dedicated circuits between Mainland China and Hong Kong: you get committed, non–best-effort bandwidth on a path that does not compete with the busiest public international internet exits at night. The cross-border access leg therefore usually stays low-latency and predictable at peak times, on carrier-grade private connectivity with the SLAs that come with it.
Important distinction: once traffic leaves our Hong Kong edge toward faraway destinations (for example services that only have a US front door), it crosses Hong Kong’s international interconnects and submarine segments. During Hong Kong peak hours, that international segment can congest. You may then notice a few sites or apps feel slower—that is usually the HK→destination path, not our Mainland–HK dedicated access “throttling.”
Major apps are generally optimized for Hong Kong and APAC with local or nearby points of presence, so day-to-day browsing rarely shows those effects. A smaller set of services that mostly live in the US and hit a busy path are more likely to feel slower at peak.
