<p class="MsoNormal">Hi all,<br>
<br>
Interesting... We (centos.mirror.digitalpacific.com.au, AS55803, 101.0.101.66) pull all of our CentOS content from centose7.centos.org (which resolves to 103.18.205.7), and we've had no problems at all.<br>
<br>
Perhaps it may be related to msync.centos.org not redirecting the requests correctly? For starters, I receive an A Record for a msync node not even local to AU:<br>

<p class="MsoNormal" style="margin-bottom:12.0pt"><br>
..and it seems to be having issues too! Perhaps that could be one of the reasons why the AU mirrors are all over the place..?<br>

<p class="MsoNormal">Greetings,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I was just wondering if there is something funny going on with msync.centos.org’s availability within Australia. I see it is geo-load balanced to various places around the world, but in particular in Australia we are (in many cases) sent

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">That’s all well and good, but a quick look at <a href="http://mirror-status.centos.org/">
http://mirror-status.centos.org/</a> reveals quite a few of the Australian mirrors have been all over the place over the last few weeks, which would somewhat suggest something is up with this mirror source?<o:p></o:p></p>
