<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Seeing many recent reports on the interwebs regarding a “nationwide Comcast outage”.<u></u><u></u></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.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></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.<u></u><u></u></p>
