Adding to the list of resources adversely affected by the Amazon Web Services outage are ScienceDirect PDFs. You can search ScienceDirect without experiencing problems but when you attempt to download an article PDF you get a blank screen or 'http error 503' message. We will send a follow-up message when the ProQuest resources are available once again. Please share this information with your colleagues.
