I've been getting same thing. Cloudflare error 520 & 522 all over the place. But only on comcast's network. Phone internet not having the issue, everything loading fine with it.

I can't get on a lot of sites. Keeps saying can't find the DNS. Some are now accessible, but still can't get others.

Now they are all back, weird.

Because you touch yourself and think of Obama when you do it!
