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.

Now they are all back, weird.

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.

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