Great to hear! I'd love for each of my site to have a dedicated IP address. It'd greatly reduce the risk of one IP getting nulled affecting other customers in the network.
Regarding DDoS attacks, it happens from time to time. As a webmaster, I do recommend you guys who are using VelocityIO to take some extra steps to prevent the problem from happening:
- use Cloudflare: Once you use it you will never think of going back. It masks your VelocityIO IP address and speeds up your website at the same time, so it's a win win win situation. Besides, vIO is a Cloudflare Optimized Partner to let you serve more traffic faster for less bandwidth, that's why I was interested in them in the first place.
- Send emails via external service: After using Cloudflare for the front end, use external SMTP for sending emails. For instance, I send email via Amazon's Simple Email Service, which is dirt cheap and it protects more sophisticated attackers from checking email source and figuring out the real IP address of my server.
- Handle your community with care: Though I am not the one to tell you how to run your community, I do encourage that you take cautions in dealing with your own community so it won't get DDoSed, it's also the courtesy for neighbors using the same shared host as yours.
I wholeheartedly trust that Max is going on the right track of providing customers, including me, with that they really need. He is steps ahead in providing sophisticated tools for you to use, so take advantage of the tools to protect your site.
