If You Experienced an Internet Outage Today, Here’s Why

There was a huge internet outage today for most users in America due to a major Distributed Denial of Service (DDoS) attack on a major Domain Name System (DNS)  provider. The company in question, Dyn Inc., began investigating the issues that began about 6am today. While the provider is actively attempting to mitigate these attacks, there is no current ETA for service restoration.

For those who may not know – DNS acts as an internet address book that translates between human language and computer addresses. Example: when you want to go to google you type in www.google.com in the address bar. DNS then says, “do I have a record for google.com? Yes, I do. Here is the IP address.”. So DNS basically translates between IP addresses and names that we like and understand. So when the DNS provider that handles requests for google is down, your computer doesn’t have any way to know where it’s going to find the webpage. Below is a map of the current outages reported for Comcast:

I will do my best to provide updates as I recieve them. Until then, you may have issues access certain websites. 

 

**UPDATE** – The outages experienced last week appear to have been caused by hacked DRV cameras in an apparent Internet of Things (IoT) attack.
