<p class="MsoNormal">We've got many internal/external monitoring alerts going off. Common factor seems to be AU DNS.<br>
<br>
Is anyone else seeing alerts tripped? Emails are flowing & I can query OK (Starlink), yet hosts remain "down".<br>
<br>
15 minutes since the first alert came through. WhatsMyDNS for "down" hosts is showing about a 50% query hit rate.<br>
<br>
Cheers,<br>
