    4 === Summary of the current situation ===
    5 As of 2017-01-17 ''Tor Browser 6.0.8'' works (no need for an obfuscated bridge; ISP: ''JSC Kazakhtelecom''), but there's an IP address blacklist that includes the torproject.org site.
    6 === First witnessed ===
     4== First witnessed ==
    75Tor blocking started between [https://metrics.torproject.org/users.html?graph=direct-users&start=2011-10-01&end=2012-05-01&country=kz&dpi=72#direct-users February and March 2012] and is mentioned in a [https://blog.torproject.org/blog/kazakhstan-upgrades-censorship-deep-packet-inspection blog post]. Another [https://blog.torproject.org/blog/updates-kazakhstan-internet-censorship blog post] was published two weeks afterwards.
    8 === Last witnessed ===
     6== Last witnessed ==
    97Sometimes around the summer of 2013 the blocking has been disabled (and an old tor bundle started to work that didn't work before).
    108
    11 In March 2015 blocking is observable again, the stock tor browser bundle cannot connect.

    13 dcf: Do you know when in March 2015 it started happening? It doesn't seem to have affected the user graph yet:

    15 
    16 In April 2015 blocking is observable again, some user reporting about problems while another still using it. User graph confirms report.

    19 Graze on, graze on, submissive nation!
    20 You will not wake to honor's call.
    21 Why offer herds their liberation?
    22 For them are shears or slaughter-stall,
    23 Their heritage each generation
    24 The yoke with jingles, and the gall.
