We had a DDOS attack on RunSignUp today. It lasted from about 4:00PM until 4:45PM when we were successful in cutting it off. It averaged over 1,000 requests per second.

The attack was looking for vulnerabilities like SQL injection. This slowed down the average response time on our website about a half second from about 2.7 seconds to about 3.2 seconds:

We will continue to watch closely for additional attacks and do everything we can to mitigate any delays or issues. We are fortunate that our Amazon AWS infrastructure is so scalable and high performing and alerts us when these types of issues occur. We also know that Amazon is also working with us on addressing these types of bad actors on the Internet.
