At CloudFlare, we're always looking for ways to eliminate bottlenecks. We're only able to deal with the very large amount of traffic that we handle because we've built a network that can efficiently handle an extremely high volume of network requests.
The New York Times this morning published a story about the Spamhaus DDoS attack and how CloudFlare helped mitigate it and keep the site online. The Times calls the attack the largest known DDoS attack ever on the Internet.
At CloudFlare, we deal with large DDoS attacks every day. Usually, these attacks are directed at large companies or organizations that are reluctant to talk about their details. Sometimes a customer is willing to let us tell their story.
CloudFlare had an hour-long outage this last weekend. Thankfully, outages like this have been a relatively rare occurrance for our service.
This morning at 09:47 UTC CloudFlare effectively dropped off the Internet. The outage affected all of CloudFlare's services including DNS and any services that rely on our web proxy.
