Hi,
I got the following in the log:
[03-Oct-2013 08:45:02 UTC] Error uploading /srv/www/site/releases/20130925144505/public/wp-content/uploads/2013/10/iPadSpringboard.png to S3: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint: “static.ourdomainhere.com.s3.amazonaws.com”.
Has something changed on Amazon side? Anything we can do, or is it something for you to fix?
