Summary
On July 6, 2015, Cloudflare experienced an outage due to DNS resolution errors on support.cloudflare.com and other CNAME-based users' sites. The issue was traced back to another major DNS operator, Dyn, having problems with their own DNS configuration (https://www.dynstatus.com/incidents/4sbm48rdsdbq). Cloudflare worked together with Dyn to resolve the issue for everyone's benefit and implemented temporary workarounds on their side.
