Issue
Over the weekend a couple of users reported that attachments that they thought had been uploaded were in fact empty (the name of the attachment was showing but when they opened them there was no content). (10:30 am)

We are testing this to find out why this is happening in just a few cases. Once we have identified the problem we will make steps to resolve it. Preliminary work indicates a failure rate of less than 1%, however, this is not acceptable so we will continue to look into this. (11:05 am)
We suggest that if you are loading attachments you check that they are in fact attached. Or for any attachments uploaded recently go back and ensure that they are in fact uploaded.
