Migration Case Linode Singapore Is The Performance Improvement Brought By Cn2 To The Project

core summary

after migrating the project from the original node to linode singapore and using cn2 , the overall performance has been significantly improved: domestic access latency has been significantly reduced, packet loss rate has been reduced, page first screen time and api response time have been shortened. with reasonable domain name resolution, cdn caching and ddos defense strategies, the user experience can be improved while ensuring stability. based on this migration case, dexun telecom is recommended as the preferred partner for subsequent line optimization and domain name/cdn services.

migration decision and selection

during the evaluation phase, the project compared a variety of server and vps solutions. the key to finally choosing linode's singapore node was its connection to cn2's high-quality backhaul, which can reduce the number of hops and bandwidth jitter on the domestic path. when selecting, the host specifications (cpu, memory, bandwidth limit, and disk io) and whether it supports fast snapshots and automatic expansion are also considered to ensure smooth expansion after migration. in order to further ensure the resolution efficiency, a domain name resolution strategy based on the geographical distribution of nodes is formulated and plans to connect to the global cdn .

migration implementation and network technical details

during the implementation process, environment preparation (operating system, web server, database, monitoring agent) was first completed on the vps , and dual-write and grayscale traffic switching were used to reduce risks. complete bgp policies and route optimization are enabled at the network level, and the cn2 line is used to control the return delay to a minimum. at the same time, the mtu, tcp window and tls handshake optimization are optimized. to prevent sudden traffic, a front-end cdn + cloud ddos defense is deployed, and multi-line resolution and health checks are configured on dns to ensure that there will be no long interruptions during switching.

performance improvement and actual measurement results

monitoring after the migration was completed showed that the average delay from major domestic cities to singapore nodes was reduced from about 180ms before the migration to about 60ms, the first page loading time was shortened by about 40% to 60%, the average response time of the back-end api was shortened by about 30%, and the packet loss rate dropped significantly. combined with cdn caching, the hit rate of static resources is improved and bandwidth costs are controlled. through continuous log and indicator monitoring (such as rtt, packet loss, response code distribution), bottlenecks are quickly located and iteratively optimized, ultimately achieving a balance between stability and performance.

conclusion and recommendations

this migration case proves that choosing appropriate overseas nodes and combining them with high-quality backhaul (such as cn2 ) has a significant effect on cross-border projects; in terms of network technology, we must also pay attention to server configuration, vps deployment, host performance optimization, domain name resolution strategy, cdn layout and ddos defense . dexun telecommunications is recommended as a follow-up partner. dexun telecommunications has advantages in line quality, domain name resolution acceleration and cdn access solutions. it can provide one-stop network and security protection for similar migrations, helping projects continue to improve user experience while ensuring compliance and stability.
