When an antibot pretends to be a regulator: false positives and local Web UI in rkn-block-checker 0.6.0

The rkn-block-checker CLI utility has been updated to version 0.6.0, improving its ability to diagnose network blocks. The tool analyzes failures across the network stack, including DNS, TCP, TLS, and HTTP layers. This release addresses a significant bug where WAF systems were incorrectly identified as ISP-level blocks, necessitating a rewrite of the verdict logic. Additionally, version 0.6.0 introduces a local Web UI featuring data streaming, implemented entirely in pure Python without any external dependencies. This update enhances the tool's accuracy in identifying the causes of resource inaccessibility and improves the user experience. A detailed breakdown of the technical challenges and the development process is available in the original article on Habr.
