Readers of Libtech may be interested in the changes to the filtering regime that were imposed a few hours ago. Currently traffic streams, at least unknown streams if not all, are being dropped after exactly sixty seconds, terminating the connection. It appears this is based on protocol rather than port, implying DPI, and thus likely to disrupt nearly every anti-filtering tool, including those that leverage obfsproxy.
