<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prefixes being withdrawn and then returning later.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withdrawn, but doesn't alert you when it comes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>
<br>
Otherwise, it seems to do the job.<br>
