If you would like additional information about what happened, I've posted a link from AWS that detailed the outage and its resolution from their side. Once it was restored from their standpoint, the vendors like Cisco and others had to bring services back online, which is why there was a delay from their fix until full service restoration. 

As always, if you have questions, please feel free to contact me for more information.
