Was there a USA nationwide DNS Outage 11.28.2018 around 6:30am ET? I ask because all sites I had open that weren't owned by multi-million dollar corps were unreachable for around 20 minutes. Even eBay went down for a couple minutes. But Google & a couple other ginormous sites never went down. Everything's ok now. But I read just from Google results with 1hr filter said it was nationwide DNS hack. I couldn't get through to those sites I just read the blurb on the results.
Funny that you say it, my internet completely died and just refused to work for 2 hours around that time. Coincidence?
