We have our own servers in a data center with 5 redundant 1 Gbps links. The DDoS was 20Gbps according to the upstream providers.&lt;p&gt;Our upstream implemented layer 7 mitigation which did an unbelievably effective job at stopping the attack in it&amp;#x27;s tracks. I don&amp;#x27;t know the tech that they used, but it performs deep packet inspection up to the application layer and they charge a modest additional fee for passing our traffic through that system.&lt;p&gt;The effect was that our traffic dropped to very slightly below normal levels during the attack, which would indicate that there were probably a few false positives, but we didn&amp;#x27;t have a single customer complaint.</text></comment>
