DNS (Domain Name Server) provider Dyn.com is currently under heavy DDoS attack (Distributed Denial of Service) which has affected many well known brands across the Internet including Amazon, Netflix, Reddit, Paypal and many others.
This morning one of my clients wrote to tell me her site was down. Fortunately it came back up fairly quickly and is fine now. However, the widespread DDoS attack which is currently underway may affect your site if you use dyn.com for DNS or if you use any service, like Paypal, that uses DynDNS.
The larger providers seem to have worked quite quickly to mitigate this attack, but it is ongoing so it’s important that you’re aware of it and carefully monitor your website during this time.
While it is a priority to protect every website I create with reasonable security measures, when there is an attack on your domain name provider there is little we can do but check in with your domain name registrar and ask them to estimate how long it will be before they can bring their service—and therefore, your own website—back online. Please contact me if you are having trouble with your website today.
Security provider Wordfence has posted on their blog with more information about this type of attack HERE.
