<p class="MsoNormal">Seeing many recent reports on the interwebs regarding a “nationwide Comcast outage”.</p>
<p class="MsoNormal">Looks like it’s an issue with Comcast DNS (75.75.75.75 / 75.75.76.76) and not anything else, as queries to other public DNS servers (ex: 1.1.1.1 / 8.8.8.8) work just fine over my Comcast service.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">For reference, I’m located in Chicago, but I did perform NSLookup’s from a box in NYC, Dallas, and Seattle which resulted in similar behavior as seen below.</p>
