Massive DDOS attack on Dynamic DNS. Lose your site today?

If your personal site such as on home server isn't getting any traffic today, the one is linked to your hostname by using Dynamic DNS settings in your router, there's a very good reason.

"A sudden outage of popular sites and services, including Twitter, SoundCloud, Spotify, and Shopify, for many users, is causing uproar online. It's because of a DDoS attack against the popular Domain Name System (DNS) service provider Dyn, according to a post on Ycombinator.

DNS act as the authoritative reference for mapping domain names to IP addresses. In other words, DNS is simply an Internet's phone book that resolves human-readable web addresses, like thehackernews.com, against IP addresses.

Dyn DNS is used by many websites and services as their upstream DNS provider, including Twitter, Spotify, SaneBox, Reddit, Box, Github, Zoho CRM, PayPal, Airbnb, Freshbooks, Wired.com, Pinterest, Heroku and Vox Media properties.

All of these sites and services are reportedly experiencing outages and downtime, either completely or partially."

And of course the map shows the outages are most prevalent in USA in the most highly populated area in the East Coast.
