It was shocked to hear that the CloudFlare CDN went down for about 30 minutes & as a result many websites (including my websites) experienced downtime! According to the tweet of @cloudflaresys, its said that they have an issue with the routing of network.
Update –> It appears to be a bad routing issue. Team is working to mitigate. Service should be coming back for all customers.
