Our hosting provider Amazon AWS is reporting wide spread issues with the Oceania (Sydney) data center which are affecting file related tasks like Previews, Zip files, etc. We are monitoring the incident with Amazon AWS (https://status.aws.amazon.com/
) and will keep this incident updated as we get more info.
In the mean time we recommend temporarily switching to the 'USA (West)' or 'S.E. Asia (Singapore)' file server regions which are unaffected.
To switch regions head to 'Manage' -> 'Account' -> 'Defaults', select your desired region then click 'Save Changes'. Note that this change only applies to new uploads.
