Web Hosting - Distributed Denial of Service attacks (DDoS) Protections

Distributed Denial of Service attacks are a common and major concern for web hosting providers. DoIT's Web Hosting Service leverages several techniques to mitigate attacks.

DoIT Web Hosting protects websites with rate limiting and other security measures, with exceptions for UW-Madison IP addresses.

Balancing the blocking of malicious traffic like DDoS attacks with the need to allow legitimate high-volume traffic requires careful management.

Protections are maintained through several layers and tools, including Palo Alto, Mod Security, Fail2Ban, and firewall protections.

If you believe legitimate requests to a DoIT Web Hosting site(s) are being blocked, please contact webhosting@doit.wisc.edu.
