What is everyone's ISP in this thread suffering from this issue? I wonder if there's some ISP commonality going on?
Unfortunately, that doesn't seem to be the case, which makes this "solution" beyond baffling.
It's good that people are adding backup DNS though (better not to rely on just one, even if it's Google), since DNS outages can and do happen. Charter Communications had a rather massive one about a week ago. Those who had backup DNS weren't affected.
