Today,  October 21st, marks the one year anniversary of the DDOS attack on Dyn. The attack impacted Dyn's DNS service, and caused degradation, or inavailability of several popular websites, including Airbnb, BBC, CNN, Paypal and many others.  The attack was attributed to the Mirai botnet of compromised Internet of Things (IoT) devices, but despite numerous investigations, the attack was not definitively attributed to any one perpetrator or group.  It did, however, highlight the fragility of the underlying Internet infrastructure, and sent a lot of service providers on a quest to shore up their pieces of that infrastructure.

Typically I have seen combinations of a few approaches.  Somehave added extra capacity.  Others have added geo-redundancy. Still others have added or increased their ability to shed DDOS traffic.  

What, if any, has your ISP done to minimize the impact of a DDOS against its infrastructure?
