Beginner's Tutorial: How To Switch To Taiwan Server At Station B. How To Switch Regional Nodes In A Few Simple Steps.

1. overview: why should site b traffic go to taiwan nodes?

1) purpose: accessing through taiwan ip can trigger bilibili’s cdn/content strategy for taiwan, thereby displaying taiwanese content or exclusive push.
2) applicable scenarios: watching region-limited content, testing playback differences between mainland china and taiwan, and debugging cdn distribution.
3) technical points: the final decision on the region is outbound ip and dns resolution. commonly used methods include vps proxy, smartdns, and vpn.
4) security and compliance: do not use it to circumvent legal or copyright restrictions, and comply with the platform and local laws.
5) performance impact: additional relays may increase delay, and bandwidth and node selection need to be made (for example, taiwan computer room bandwidth is generally recommended to be ≥100mbps).

2. comparison of common solutions and their pros and cons

1) taiwan vps+socks5/ssh tunnel (advantages: simple, controllable delay; disadvantages: server management required).
2) wireguard/openvpn (advantages: system-level proxy, stable; disadvantages: slightly complicated configuration, occupying server resources).
3) smartdns (advantages: only changes dns, does not use full traffic, low latency; disadvantages: not always effective for encrypted domain names/https).
4) commercial vpn (advantages: easy to use; disadvantages: poor controllability, speed and privacy vary by provider).
5) selection suggestions: put low latency and stability as the first priority. if you only browse videos, you can give priority to smartdns or socks5; if you need to travel globally, you can use wireguard.

3. practical steps (using taiwan vps+ssh socks as an example)

1) purchase taiwan node vps: you can choose google cloud asia-east1 (taiwan) or a hosting provider that supports taipei computer rooms. the sample configuration is in the table below.
2) server initialization: set root password/ssh key, turn on the firewall, and only open port 22 (or custom management port).
3) establish a socks5 tunnel: run the command example locally: ssh -d 1080 -c -q -n root@server_ip (the example command is used to create a socks proxy for the local 1080 port).
4) browser configuration: set the browser proxy to socks5 127.0.0.1:1080, or use plug-ins such as foxyproxy to switch rules.
5) verify the region: visit https://ipinfo.io or https://whatismyipaddress.com to confirm that the taiwan ip is displayed, then open station b to confirm the region and playback node changes.

4. real cases and performance data (demo)

1) case background: user a is in shanghai and aims to view test manuscripts that are only open to taiwan through the taiwan node.
2) selected node: google cloud asia-east1 (taiwan) virtual machine, configuration: 2 vcpu / 4gb ram / 1gbps bandwidth (specifically listed in the table below).
3) latency comparison (example measurement): direct connection (shanghai isp -> station b default cdn) average rtt ≈ 35ms; average rtt to taiwan cdn via taiwan vps proxy ≈ 90ms (actually affected by routing, may be different).
4) actual effect: after accessing through taiwan ip, the hdr/region label switching of station b is successful, and the video can be played without significant loss of clarity (provided that the bandwidth is sufficient).
5) note: if playback buffering occurs, you can increase the vps bandwidth or combine local cdn/caching strategies to reduce cross-border bandwidth bottlenecks.

6. cdn, domain name resolution and ddos defense suggestions

1) cdn strategy: if you operate domain names or self-built services, using anycast cdn can reduce cross-border delays and improve availability; offload video to taiwan edge nodes.
2) domain name resolution: smartdns or self-managed dns (dnsmasq) can point to taiwan cdn ip for specific domain names, reducing overall vpn traffic.
3) ddos protection: for external services, it is recommended to connect to cloud protection (such as cloudflare, akamai or cloud vendors’ own ddos) to prevent node unavailability due to large traffic attacks.
4) high availability and monitoring: configure dual nodes (taiwan + other nearby regions) for health check and bgp/load balancing, and use prometheus/cloud monitoring to observe bandwidth and number of connections.
5) backup and compliance: back up key configurations and logs regularly, follow the terms of use of the service provider and platform, and avoid abuse that may lead to account closure or legal risks.

7. frequently asked questions and troubleshooting suggestions

1) unable to connect to ssh: check whether the cloud console firewall/security group has released the corresponding port, and confirm whether the local network is restricted by the local isp.
2) the original region is still displayed after proxying: clear the browser cookies/cache and confirm that the dns is not hijacked by the local resolver (can be tested with 1.1.1.1/dns-query or 8.8.8.8).
3) playback freezes: check the vps bandwidth usage, packet loss rate and delay, and upgrade the bandwidth or enable multi-node load if necessary.
4) the service is under attack: enable cloud vendor ddos protection, limit useless ports, use rate limits and waf.
5) logs and auditing: keep connection logs for troubleshooting, but pay attention to privacy and related legal compliance requirements.
