Today Amazon suffered a major failure on 1 of their online services. The S3 services in the US-East1 (North Virginia) became unresponsive. The outage lasted several hours and impacted some quite large names.
So why am I raising this here? The region impacted is in fact the region primarily used for hosting Alexa Skills (the only other option is Ireland) there is potential that some skills were affected by the issue. Up until recently the North Virginia location was the only possible data center set that an Alexa skill could be hosted however this has now expanded ito Ireland.
