Fresh insights from old data: corroborating reports of Turkmenistan IP unblocking and firewall testing

Summary

The article discusses the recent unblocking of over 3 billion IP addresses in Turkmenistan and the implications of this event on internet traffic and firewall behavior. It leverages historical data from Cloudflare Radar to analyze TCP connection resets and timeouts, which serve as indicators of network behavior and potential firewall testing. The analysis reveals significant trends in connection anomalies, suggesting that the observed changes in traffic patterns correlate with the unblocking of IPs and the testing of new firewall systems. The article emphasizes the importance of context in interpreting these data trends and encourages further exploration of historical data to gain deeper insights into network behaviors.

Key Learnings

• 1TCP connection resets and timeouts can indicate underlying network behaviors, such as the testing of firewalls.
• 2Analyzing historical traffic data provides context that can help corroborate reports of network changes.
• 3The proportion of TCP anomalies can shift significantly based on user behavior and network configurations.
• 4Understanding the limitations of passive data observation is crucial for accurate interpretation of network events.
• 5Correlation between increased HTTP requests and TCP anomalies can suggest significant changes in network access policies.
