			<content:encoded><![CDATA[<p>My ISP, <a href="http://www.enta.net/">entanet</a>, has yesterday taken the bold, and equally brave, move of <a href="http://noc.enta.net/?page_id=215">publishing the ADSL BRAS profiles of their customer base</a> as an MRTG style graph.  The move is brave because ISPs are coming under strong pressure from the regulator OFCOM to explain <a href="http://www.bit-tech.net/news/2007/10/10/uk_isps_quizzed_over_advertised_broadband_speeds/1">why customers are not getting the speeds advertised</a>.  IT new-site, The Register, <a href="http://www.theregister.co.uk/2007/08/07/which_broadband_survey/">has covered this story with an equal blaze of publicity</a>.  </p>
<p>Here&#8217;s a recent image of the graph [it updates every hour].</p>
<div style="text-align: center;">
<a title="Enta BRAS Profile Graph"><img src="http://farm3.static.flickr.com/2402/1613492065_12c5926517_o.png" width="450" height="245" alt="bras-profile" /></a>
</div>
<p>&nbsp;<br />
Three things strike me first off about this graph:</p>
<ul>
<li>The lack of a <a href="http://en.wikipedia.org/wiki/Bell_curve_grading">bell curve</a>. Though, I would explain this by noting that given the percentage of people able to obtain very close to the 8128 maximum sync rate is 37.8% &#8211; not the fairest, or most even, distribution of spread.   Remember,  Enta is a professional ISP attracting net-savvy users; I would hazard a fair guess that a lot of people specifically move to a location that is in good reach of their local exchange &#8211; I know i did.    When BT releases <a href="http://www.btplc.com/21CN/">21cn</a> i would expect a bell curve to exist around the 6000-10000 mark. Only time will tell, mind.
  </li>
<li>As referred to above, <a href="http://www.which.co.uk/">Which?</a> magazines <a href="http://www.bit-tech.net/news/2007/08/02/uk_isps_under_fire_for_false_advertising/1">continued insistence that broadband provider&#8217;s are setting too high a customers&#8217; expectation</a> as to speed&#8217;s possible on their ADSL line  appear to be inaccurate.  Setting aside the reasoning for the graph&#8217;s data in point 1, there is a significant proportion of customers on a very acceptable BRAS profile.
<p>    My personal opinion is that Which? magazine is making an issue where there is none.  I have never experienced an ISP stating that they <b>will</b> provide 8mbit services, but rather <b>can</b> provide, if your line is suitable.  If I was a cynic I would state that Which? are creating publicity for themselves by writing these reports. Unfortunately, I am only adding to their publicity.
  </li>
<li> Not directly related to the graph, but to the ISP publishing it: Enta have taken an exceptionally positive step in publishing this data.  At a time when ISPs are under-fire (see above), they have chose to make their data public for the world to inspect.  Well done, Enta!<br />
&nbsp;<br />
<b>NB:</b> I fully recommend Entanet reseller, <a href="http://www.ukfsn.org/">UK Free Software Network</a>.
 </li>
</ul>

			<content:encoded><![CDATA[<p><a href="http://www.alexa.com/">Alexa</a> has released the latest 2007 <a href="http://royal.pingdom.com/?p=134">downtime statistics</a> for the web&#8217;s most popular sites.  We all strive for maximum uptime, but it&#8217;s a slightly re-assuring to know that even the world leaders still can&#8217;t achieve 100% uptime all of the time.  99.999% is a realistic figure, mind.</p>
<p>Whilst we&#8217;re on the subject of downtime, this link details <a href="http://royal.pingdom.com/?p=130">the average website downtime for 2007</a></p>
<blockquote><p>
The average website downtime in April was almost exactly two hours.</p>
<p>March 2007: 119 minutes (99.73% uptime)<br />
April 2007: 120 minutes (99.72% uptime)
</p></blockquote>
<p>Quite interesting statistics, I thought!</p>

			<content:encoded><![CDATA[<p><strong>S</strong>pent the last hour setting up <a href="http://awstats.sourceforge.net/">AWStats </a>on my Ubuntu server.  What&#8217;s annoying is that the package is pre-configured for Apache &#8212; I completley understand why this is done, but when you don&#8217;t run Apache it is slightly irritating.</p>
<p><strong>Things to note when <u>not</u> running Apache:</strong></p>
<p>Make sure that <code>/var/lib/awstats/</code> is <code>chmod'ed</code> to permissions that your webserver can read from.  Here&#8217;s the cron code I used to make sure awstats updates itself every 10 minutes:</p>
<p><code>0,10,20,30,40,50 * * * * nobody [ -x /path/to/cgi-bin/awstats.pl -a -f /etc/awstats/awstats.conf -a -r /path/to/access.log ] &amp;&amp; /path/to/awstats.pl -config=&amp;lt;domain name&amp;gt; -update &gt;/dev/null</code></p>
<p>My webserver is securely running as <code>nobody</code> so it&#8217;s important the we use the same user to perform the cron job to update awstats&#8217; datafile.</p>
<p>As mentioned previous, the important part here is making sure that this cron job can update files within <code>/var/lib/awstats/</code>.  A <code>chmod 640</code> will provide ample security here, allowing the webserver user to read and write, as well as allowing the group to read the file.</p>
<p>That all done, AWStats is now <a href="/awstats/">up and running</a> and providing some interesting statistics..! ;)</p>
