title: pear.php.net is down. How to install mirror?
body: <p>I was trying to install new packages in my PHP environment development via PEAR but as shown below:</p>
  
  <pre><code>File http://pear.php.net:80/rest/p/packages.xml not valid (received: HTTP/1.1 404 Not Found)
  </code></pre>
  
  <p>it seems that <code>php.net</code> is down.</p>
  
  <p>I tried to setup a mirror since <code>us.php.net</code> which Digg hosts with the following command:</p>
  
  <pre><code>pear config-set preferred_mirror us.pear.php.net
  </code></pre>
  
  <p>which gives the following error:</p>
  
  <pre><code>Channel Mirror "us.pear.php.net" does not exist in your registry for channel "pear.php.net".
  Attempt to run "pear channel-update pear.php.net" if you believe this mirror should exist as you may have outdated channel information.
  </code></pre>
  
  <p>Of course I can't update the channel since <code>php.net</code> is down.</p>
  
  <p>Does anyone know how i should proceed?</p>
