Actual Combat Test Report: Tank World Blitz – Assessment of Connection Stability on German HT Server

Introduction: Based on multiple rounds of actual combat and tool sampling, this paper focuses on evaluating the connection stability of the German HT server in World of Tanks Blitz. The report is aimed at players and operations staff, aiming to illustrate server performance with quantifiable metrics and provide actionable optimization suggestions.

Test Purpose and Environment

The purpose of this test is to evaluate the connection stability of German HT (High Tier) servers in real-world scenarios. The testing sampling scope includes European backbone routes, multi-regional player nodes, and different time periods. Common network monitoring tools and in-game logs are used as data sources to ensure that the results are comparable and representative.

Testing Methods and Key Metrics

The testing method combines active and passive monitoring: Proactively use ICMP/UDP probing and multi-threaded concurrent connections for simulation ； Passively collect in-game latency and packet loss logs. The key metrics are average latency, jitter (variance of latency), packet loss rate, and frequency of connection interruptions, all analyzed on a per-minute and per-hour basis.

Network latency and packet loss performance

During normal times, the median latency of German HT servers remains within acceptable ranges, with jitter staying low most of the time. During peak times or when there is long path latency, there will be increased delays and occasional packet losses. The packet loss is usually within 0.5%, and it manifests as stuttering in the video or delays in skill commands.

Observations of stability under high load

Simulations of large-scale concurrent battles and high-frequency reconnection scenarios show that the server can maintain connections in the short term, but jitter and packet loss rates increase significantly. If the back-end links or edge nodes are congested, individual sessions may experience disconnections on a second-by-second basis, indicating a need for further optimization in high-load strategies and traffic shaping.

Regional Differences and Local Network Influences

There are significant regional differences; players near Europe’s backbone network experience lower latency and more stable performance. Conversely, nodes that are cross-border or routed through multiple hops are more prone to jitter and packet loss. Therefore, the local network quality on the player’s end, routing policies, and ISP links have a significant impact on the overall experience, and it cannot be attributed solely to the server side.

Summary and Recommendations

Summary: The evaluation of connection stability on the German HT server in this World of Tanks blitz show that the server performs stably under normal load, but experiences latency and short-term packet loss fluctuations during peak times or cross-regional access. It is recommended that the operations team improve peak traffic scheduling, optimize routing, and enhance monitoring and alerting ； Players can prioritize using low-latency paths or adjust network settings to improve the experience.
