+    <small><em>The performance improvements that were implemented in the

+    last phase have been released in Tor version 0.2.1.7-alpha. Users can

+    download this development version from the Tor homepage and test the

+    improvements with minimal effort. Further, two bugfixes (<a

+    href="http://bugs.noreply.org/flyspray/index.php?id=767&do=details">1</a>,

+    <a href="http://bugs.noreply.org/flyspray/index.php?id=814&do=details">2</a>)

+    that were found in the course of this project have been backported to

+    the stable branch and will be included with the next stable version

+    0.2.0.32.</em></small>

+    <br/>

+    <small><em>The main focus of the past 31 days was to perform new

+    measurements to see whether the improvements are effective or not.

+    Measurements were conducted for two days in the time of November 6th to

+    8th. Unfortunately, the Tor network suffered a serious problem in this

+    time: An expired directory authority certificate produced huge amounts

+    of traffic within the Tor network which <a

+    href="http://archives.seul.org/or/talk/Nov-2008/msg00053.html">forced

+    many operators to shut down their relays</a>. A second measurement was

+    performed between 13th and 15th. But results show that the overall

+    network performance is still worse than in June 2008 when the first

+    hidden service measurements have been performed. This becomes visible

+    when comparing requests to the Tor directories which have not been

+    affected by the performance improvements and which exhibit

+    significantly worse performance than before. The effects of performance

+    improvements are visible, but absolute values are not comparable at

+    this time. New measurements will be conducted in December in the hope

+    that the effects of this problem have mitigated.</em></small>

+    <small><em>Further, there might be a <a

+    href="http://bugs.noreply.org/flyspray/index.php?id=847&do=details">bug</a>

+    in the way how Tor downloads directory information during

+    bootstrapping. Even though this is not related to hidden services, an

+    improvement would benefit hidden service publication, too. Part of the

+    work during the upcoming 30 days will be to investigate this bug.
