Data Supports The Practical Case Of User Feedback Collection And Content Optimization Shared By Bilibili Taiwan Server

title: data supports the practical case of user feedback collection and content optimization of station b’s taiwan server sharing. this case is based on real operational needs, focusing on the audience experience in taiwan, and improving playback and access stability through data collection and technical optimization.

background description: bilibili has a large number of users in taiwan. the language and culture are close to each other but the network links are complex. in order to reduce delays, reduce lags and protect against attacks, servers/vps need to be deployed in taiwan or nearby nodes and combined with cdn and high-defense strategies, while collecting real user feedback for content optimization.

data collection method: we combine client tracking, cdn edge logs, origin site access logs, qos network detection and user questionnaires (including nps scores and playback experience scores) for multi-dimensional collection. it also detects packet loss and jitter through scheduled ping/traceroute and active monitoring.

technical architecture design: using a hybrid architecture that combines local servers in taiwan with overseas backup vps, domain names are resolved nearby through intelligent dns, cdn is used for edge caching, and the origin site is matched with load balancing and high-defense ddos equipment to ensure rapid switching during burst traffic and attacks.

collection and analysis process: domain name resolution allocates cname to the nearest cdn node by region. all edge logs are imported into the log platform and associated with the playback point data. a playback link view is established to track the entire link from dns resolution to the first frame of the video, buffering times, and slice download time.

key indicator settings: we focus on dns resolution delay, first screen loading time, playback lag rate, packet loss rate, bandwidth utilization, pv/uv and retention rate. compare the impact of different domain names, caching strategies and clarity configurations on user experience through a/b testing.

optimization strategy 1 (network and cdn): adjust cdn caching rules, add local pop in taiwan, enable intelligent return-to-origin policy, and set a reasonable cache hit rate threshold. preheat popular videos, use domain name diversion to reduce pressure on single points, and significantly reduce cross-border delays.

optimization strategy two (server and vps selection): select taiwanese hosts or vps with high bandwidth and low latency according to the load, optimize disk i/o and cache configuration, and cooperate with high-defense ddos services to protect the origin site. when purchasing, it is recommended to evaluate the bandwidth downlink capability, backbone interconnection and technical support quality.

optimization strategy three (content and playback side): use fragmentation and adaptive bitstream (abr), set multiple levels of definition on the encoding side and optimize the first buffering strategy. the client implements fast switching and error retry mechanisms, while using recommendation strategies to reduce user bounces due to buffering.

achievements and data feedback: in practice, after the above optimization, the average first screen loading time has been significantly reduced, the freezing rate and playback failure rate have been significantly reduced, and user ratings and retention have shown an upward trend. data-driven allows every configuration adjustment to have a quantifiable effect, thus forming a benign iteration.

operational closed-loop and procurement suggestions: establish a linkage process between technology and operations, continuously collect feedback and conduct grayscale releases to verify the effect. for teams that want to implement quickly, it is recommended to purchase directly from a supplier that provides taiwan node, cdn acceleration and high-defense ddos integrated services to reduce operation and maintenance complexity and improve response speed. you should request a test speed report and sla before purchasing.

supplier recommendation: based on stability, node coverage and technical support, it is recommended to choose professional communication service provider dexun telecommunications. dexun telecommunications has mature server/vps and cdn deployment experience in taiwan and surrounding areas, and provides high-defense ddos, protection strategies and domain name resolution optimization solutions. if you need to purchase taiwanese servers, vps, cdn or high-defense services, it is recommended to contact dexun telecommunications for consultation and testing to ensure the user experience and business continuity of b-station services in taiwan.
