Research: Tail Attacks on Web Applications
When you think of a Distributed Denial of Service (DDoS) attack, you probably think about an attack which overflows the bandwidth available on a single link; or overflowing the number of half open TCP sessions a device can have open at once, preventing the device from accepting more sessions. In all cases, a DoS or DDoS attack will involve a lot of traffic being pushed at a single device, or across a single link.
TL;DR
- Denial of service attacks do not always require high volumes of traffic
- An intelligent attacker can exploit the long tail of service queues deep in a web application to bring the service down
- These kinds of attacks would be very difficult to detect
But if you look at an entire system, there are a lot of places where resources are scarce, and hence are places where resources could be consumed in a way that prevents services from operating correctly. Such attacks would not need to be distributed, because they could take much less traffic than is traditionally required to deny a service. These kinds of attacks are called tail attacks, because they attack the long tail of resource pools, where these pools are much Continue reading

Norfolk and Richmond, Virginia: Cloudflare’s 152nd and 153rd cities
Virginia has a very important place in Internet history, as well as the history of Cloudflare’s network.
Northern Virginia, in the area around Ashburn VA, has for a long time been core to Internet infrastructure. In the early 1990’s, MAE-East (Metropolitan-Area-Exchange East) , an Internet Exchange Point (IXP) was established. MAE-East and West were some of the earliest IXPs. Internet Exchange Points are crucial interconnection points for ISPs and other Internet Networks to interconnect and exchange traffic. Eco-systems have grown around these through new data center offerings and new Internet platforms. Like many pieces of the Internet, MAE-East had a humble beginning, though not many humble beginnings grew to handle around 50% of Internet traffic exchange.
Cloudflare’s second Data Center, and one that still plays a critical component in our Global Network was Ashburn, Virginia. Similarly across many organizations, the Northern Virginia area has become a Data Center mecca. Many of the largest Clouds have a substantial amount of their footprint in Northern Virginia. Although MAE-East no longer exists, other Internet Exchange Points have come and grown in its place.
Cloudflare’s network has grown beyond what was traditional Interconnection points, like Ashburn/Northern VA, to a new Edge of the Continue reading
