According to Wikipedia, "as of 2017, Cloudflare provides DNS services to 12 million websites". It is being widely reported thousands of sites are unavailable due to an outage at Cloudflare. Looking at the Newslookup.com crawler so far today I am finding about 40 news sites out of 1500 aggregated today are unreachable due to the problem at Cloudflare.
Cloudflare Status reports. https://www.cloudflarestatus.com/
I will provide updates here on site availability related to this issue.
