    <div class="moz-cite-prefix">Hi Ross/Nathan,<br>
      <br>
      These aren't new prefixes advertised from an AS, they're existing
      prefixes being withdrawn and then returning later.  I get an alert
      email each time a prefix disappears, but no end of alert email
      when it comes back.<br>
      <br>
      I also get alerts quite a lot about other parts of the world (esp.
      Brazil, North America, and Northern Europe) not being able to see
      our prefixes, even though they're advertised to our providers and
      visible domestically.  e.g. Here's our AS viewed from 3
      route-views servers as of yesterday:<br>
      <ul>
        <li><a class="moz-txt-link-freetext" href="http://paste.debian.net/hidden/524ca085/">http://paste.debian.net/hidden/524ca085/</a></li>
      </ul>
      <a class="moz-txt-link-freetext" href="http://bgp.he.net/AS132897">http://bgp.he.net/AS132897</a> shows it fine as well.  Yet, there are
      presently 3 active alerts for prefix 103.27.153.0/24 in my BGPmon
      account, one going back to 20 December.<br>
      <br>
      I probably should contact BGPmon about these rather than whining
      to you guys about it. <span class="moz-smiley-s3"><span> ;-)   </span></span> 
      Writing email now...<br>
      <br>
      Regards,<br>
      Paul<br>

                        I've been trialling BGPmon over the last few
                        months as well.  One of the things I don't like
                        about it is that it emails you when a prefix is
                        withdrawn, but doesn't alert you when it comes
                        back.<br>
