I contacted the Support team at Open Library and this is what they said:

Hi and thank you for contacting us.
No, it doesn't seem like it is working properly. However what we're getting is an intermittent error and so we're not sure what's not working. We've been collecting a list of items that are unable to be downloaded and are looking for a pattern.
Thanks for using openlibrary.org and archive.org

Topic: Borrowing Books
Description:
Is the server working properly? I cannot download from Adobe Digital Editions. It is giving me E_ADEPT_DATABASE which means the server is not responding to Adobe's request.
Please check your PDF and Epub servers. I can view the file on my internet browser but I prefer to read it in Adobe Digital Editions. Thanks!
