DNS Outage Impacting Several Major Websites

Due to a global Distributed Denial-of-Service (DDoS) attack against the DNS infrastructure of Dyn, Inc. (see press release), several major internet sites are suffering from varying degrees of outage this morning (Friday, October 21st, 2016). Affected sites suffering from the outage which may impact our clients’ businesses include:

  • PayPal
  • Shopify
  • Twitter
  • Spotify
  • … and many others.

This outage seems to be affecting customers primarily on the U.S. East Coast. Users accessing these sites might have more or less success depending on where they’re located, as some European and Asian users seem not to be encountering these issues.

DNS Outage Impacting Several Major Websites due to a massive DDoS attack against Dyn, Inc.

A DDoS attack occurs when computers flood targets systems with spurious requests. In this case, the attack is targeting the Domain Name System (DNS) of a major DNS provider. This system is responsible for converting friendly domain names such as bcsengineering.com into the IP addresses of the destination computers which host that sites services.

As of 9:15am EDT, Dyn, Inc. has announced that they have restored full DNS functionality.

Expect for some minor issues to continue throughout the morning as sites work to address follow-on issues related to the outage, however, we expect things will be back to normal relatively soon.

If you are experiencing issues with any X-Cart modules built by BCS Engineering, such as the PayPal DPM module, please contact via our support ticket system.
