Apologies for the service interruption. Our new Virtual Machine Environment hiccuped this morning, and we’re shaking out the process we need to go through to restart everything smoothly. Covers should be being served normally from covers.openlibrary.org using ISBN or other supported identifiers.
I’ll update here if there’s relevant news – hopefully it won’t be down much longer.
Update, 4:00PM PST: OK. We’re stable again now. Damn race conditions in Linux kernels!
Update, 10:00PM PST: The website is down again.
Update, May 17 2:00AM PST: We’re back online now. But, covers.openlibrary.org is offline, which unfortunately means that external sites accessing Open Library covers using ISBNs is also offline. Covers on openlibrary.org are being served from an alternate location. (We need to wrangle some DNS settings to get this fixed, hopefully within a few hours.)
