<p class="MsoNormal">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These aren't new prefixes advertised from an AS, they're existing prefixes being withdrawn and then returning later.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:<o:p></o:p></p>
<ul type="disc">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
<a href="http://paste.debian.net/hidden/524ca085/">http://paste.debian.net/hidden/524ca085/</a><o:p></o:p></li></ul>
<p class="MsoNormal"><a 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> 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 One of the things I don't like about it is that it emails you when a prefix is withdrawn, but doesn't alert you when it comes back.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>
<br>
Otherwise, it seems to do the job.<br>
