Cloudflare has also been nailed the last 3 weeks in a row causing outages. Just search Twitter for cloudflare DDOS or NTP or etc. etc. etc. At the end of the day there are currently so many slave machines out there we are all vulnerable. It's just the nature of things. At least outages are only temporary. It's much better than the early days were we'd be down for 12 hours at a time. https://twitter.com/search?q=cloudflare%20attack&src=typd
