100mb/s upgrade to 1gbps network - To Prevent DDOS [duplicate]

You should be working with your hosting company to mitigate the attack.

They likely have other resources and means with which to deal with a DDOS attack. It is better handled at the network edge rather than the target.

Umm... No. Having a bigger pipe doesn't do anything to prevent the traffic or the attack. You may reduce the impact, but you're not fixing anything by installing a 1Gbps NIC.

A solution to this is CloudFlare. It acts as a reverse proxy for your site and blocks DDoS attacks. It can also perform security checks and reputation checking for the IPs trying to access your site.
