Ask HN: Anybody experiencing DNS issues?

Since this morning my website is experiencing DNS issues, it almost never resolves. A lot of people are complaining to Namecheap that their DNS doesn't work. Namecheap originally told it was them, then said it is comcast and now says everything's in order on their end. Yet, people are complaining DNS are not working. On my end the traffic to my website is close to 0. Is there a worldwide issue going on?
