Kazakhstan (#6140)

Summary of the current situation

There's an IP address blacklist, but tor seems to work.

First witnessed

Tor blocking started between February and March 2012 and is mentioned in a blog post. Another blog post was published two weeks afterwards.

Last witnessed

Sometimes around the summer of 2013 the blocking has been disabled (and an old tor bundle started to work that didn't work before).

Types of Tor censorship

  • Deep packet inspection: #6140
    • Fingerprint: The TLS client cipher-list in the ClientHello record, parts of the Tor TLS server hello record, and probably more fingerprints in other nearby TLS records.

Types of non-Tor censorship

Ways to bypass censorship

Type of firewall

  • Unknown.
