Quick question for you all. Just two days ago I registered two domain names at dynu (not dyn). Early this morning I a cold call from a company in India who knew the domain names and my phone number and was calling to ask if I wanted them to help me manage my website cheaply. Also, this morning I got a spam text from someone who claimed to by godaddy offering the same thing. Now I protect my number really well so this is the first time in 5+ years that I ever got spam texts or calls to my number. Do you think Dynu was also hacked?! Or maybe Dynu sells client numbers (which is how the guy in India claimed to get my number) and it was just by random chance that this happened at the same time as the Dyn hack.
Agree with shortstuffsushi that this is just someone getting your domain name info and spamming you. It sadly happens all the time.
Go to http://whois.icann.org/en and enter your domain name and see what info is public about you. If all your info is public, you may want to see if your registrar offers "private" registration where your info does not appear in WHOIS.
Fwiw, this isn't a hack, this is a DDoS (denial of service). It seems almost certain that your information was either given out by dynu, or your WHOIS record isn't protected. Check your domains out with your favorite WHOIS tool first. Otherwise... time for an awkward conversation with dynu.
