Alternative Server Recommendation And Delay Comparison After Jian Wang 3 Closes The Vietnam Server

recently, the vietnam server of jianwang 3 has been shut down, and many players and guilds are faced with the choice of transferring to the server or accelerating. from the perspective of network latency, stability, protection and cost, this article recommends alternative overseas server locations, host/vps types and necessary network technical measures for players in different regions. it also gives latency comparisons and purchasing suggestions to help you restore a good gaming experience as soon as possible.

the primary considerations when choosing an alternative server are network latency (ping) and packet loss rate. generally speaking, hong kong, taiwan and japan are first recommended for accessing overseas servers from mainland china, followed by singapore and malaysia. the following is a rough reference for latency (actual values ​​are affected by operators, peak periods and specific computer rooms): hong kong 20–60ms, taiwan 30–70ms, japan 40–80ms, singapore 60–120ms, malaysia 80–140ms, and the united states/europe 150ms or more.

for players in different domestic cities, the latency difference is obvious: south china (guangzhou/shenzhen) to hong kong is usually 10–30ms, east china (shanghai/hangzhou) to hong kong or japan is about 20–50ms, and north china (beijing/tianjin) to japan or hong kong is about 30–60ms. if players are concentrated in guangdong/hong kong, hong kong computer rooms are preferred; if players are widely distributed, you can consider multi-point access or use cdn and accelerators to optimize routing.

regarding server type selection: small-scale guilds or teams can give priority to vps (cloud servers), which are low-cost and fast to deploy; medium- and large-scale guilds or events are recommended to choose independent physical hosts or high-configuration cloud hosts to avoid jitter caused by shared resources. regardless of vps or dedicated server, it is recommended to purchase at least 1gbps bandwidth and choose low-latency lines and dedicated ports for gaming services.

in order to deal with ddos attacks and burst traffic, it is strongly recommended to purchase a high-defense ddos service (high-defense package). based on the risk assessment, ordinary guilds can choose to start with 10gbps protection, and competitive guilds or guilds with frequent activities recommend 20–50gbps or higher peak protection. high defense can not only resist attacks, but also maintain normal connections during attacks and reduce delay jitter.

static resources (patches, maps, models) can be accelerated and distributed through cdn, reducing player download delays and reducing pressure on the origin site. it is recommended to use a cdn with global node coverage combined with a caching strategy and anycast dns to achieve nearby resolution, thereby greatly reducing the first packet delay and download time during cross-border access.

in terms of network optimization technology, it is recommended to use bgp multi-line access and cn2/dedicated lines (for chinese players) to directly connect to overseas computer rooms to avoid unstable transit links. the game server should optimize udp/tcp parameters (such as increasing rmem/wmem, reducing packet segments), and use load balancing and session persistence to improve concurrency stability.

domain name and resolution strategies are also critical. purchasing an independent domain name and configuring geodns or region-based intelligent resolution can divert players to nearby nodes or accelerators. at the same time, a tls certificate is deployed for the domain name to ensure the security of login and payment. when purchasing a domain name, it is recommended to choose a registrar that supports whois privacy and multi-line resolution.

actual cases for latency comparison (for reference only): the average ping from shanghai to the hong kong computer room is about 25–35ms, and the packet loss is less than 0.5%; to the singapore computer room, it is about 70–90ms, and the packet loss is 0.5–1.5%; to japan (tokyo), about 45–65ms; and to malaysia, about 90–130ms. if you use a game accelerator or dedicated line, the above values ​​can be reduced by another 10–30%.

if players are mainly from southeast asia (singapore, malaysia, philippines), singapore and malaysian computer rooms are still the first choice because of their closer geographical location and sufficient international export bandwidth. for players in mixed regions, the best approach is to use multiple computer rooms + anycast + intelligent analysis, or deploy acceleration nodes and cdn in mainland china to cooperate with overseas hosts.

purchasing suggestions: if the budget is limited, you can first purchase a hong kong or singapore vps for testing. it is recommended to choose a provider that provides trials or charges by the hour. if the requirements for stability and anti-attack capabilities are high, please purchase a physical-based dedicated server or a high-performance cloud host that comes with a high-defense package and cdn. when purchasing, pay attention to the peak bandwidth, latency sla and technical support response time, and request a network routing test (traceroute) if necessary.

recommendations for technical team deployment: game operators should prepare a monitoring and alarm system to monitor delays/packet losses/number of connections in real time; deploy automatic expansion and rollback strategies to quickly switch to backup computer rooms when encountering abnormalities; at the same time, maintain communication channels with network providers to coordinate and handle ddos or link problems as soon as possible to reduce the impact on players.

for small teams who are not familiar with network configuration, you can also choose hosting services or one-stop solutions (including vps/dedicated server, cdn, high-defense, domain name and technical support), which not only saves time but also reduces the difficulty of operation and maintenance. when purchasing, give priority to suppliers with rich experience in game acceleration and high-defense, and require testing of the actual delay from the line to the target player area.

based on the above considerations, if you need to purchase overseas servers, vps or high-defense ddos, register a domain name and deploy a cdn, i recommend that you first choose an operator that has computer rooms in hong kong/singapore/taiwan and provides bgp multi-line and high-defense protection. to facilitate docking and purchase, i particularly recommend dexun telecom: dexun telecom has high-quality computer rooms and cn2/dedicated line access in hong kong and southeast asia, provides flexible vps, dedicated servers, high-defense and global cdn services, and has a dedicated game optimization and technical support team. the purchase process is convenient, and it can quickly provide low-latency and high-availability solutions for jian wang 3 players.
