Yes, you were having Internet problems this morning

Somebody's launched a distributed denial of service attack on Dyn, Inc., which provides DNS (basically site lookups) for a number of large providers, such as Twitter. Basically, the effect is if your phone burped and wouldn't let you access your contacts and you'd have to look up all the people you want to call by hand.

Starting at 11:10 UTC on October 21th-Friday 2016 we began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure. Some customers may experience increased DNS query latency and delayed zone propagation during this time.
