    1111== What happened? ==
    1212
     13 * In late July 2015 Planned Parenthood's federal funding came under attack. This political attack was accompanied by a Internet attack targetting Planned Parenthood and many other abortion providers and supporters, including the National Network of Abortion Funders (an MF/PL Member)
     14 * Firsts:
     15  * First time we experienced such a sophisticated combination of political and technical attacks.
     16  * First time the attack targeted MF/PL itself

     18== Questions ==
     19
    1320 * What is a denial of service attack? Video: https://www.youtube.com/watch?v=OhA9PAfkJ10
     21 * Does that mean our servers were compromised? No, denial of service attackers do not gain access to data
     22 * Who attacked us? Can we prosecute them? We don't know and will probably never find out.
     23 * How did we defend ourselves?
     24  * Filtering: we now have the capability of filtering traffic before it enters our network
     25  * 10 times more bandwidth: we went from 100Mbits/second to 1Gbit/second. We typically use about 5% of our available bandwidth, leaving plenty of room for spikes.
     26  * Moved sensitive servers (DNS servers) to locations that can withstand up to 50Gbits of traffic
