Amazon systems, of which we use the Amazon S3 service for most sites, have been having varous outages throughout the day.
This may have effects on various parts of web sites, from automated backups to file availability (for larger file downloads and uploads) on your site.
The issue is system-wide effecting many sites around the country (and world), including Amazon.com itself.
This is NOT directly effecting any of our hosted websites themselves, only various functionalities.
As this is a system failure with Amazon we are unable to do much to resolve this, and we expect that once the issue is resolved things should resume working as they should.
We will post a new note when we see all issues resolved.
