Ideally we should figure out what happened, and try and prevent other upload from failing in a similar way

This is probably not really "high" priority as it appears to be an isolated incident. Would still be nice if we could figure out what happened though.

To me it's high as long as it's fresh and there's logs.
It'll get lower priority if nobody investigates soon'ish.

So much for being isolated. From commons:vp

Description pages will no longer be created on backed errors.

The underlying errors are sporatic HTTP 401s that happen (due to very premature token expiration or validation errors for some reason...possibly internal memcached problems in Swift).

I don't know whether it is useful information, but deleting and restoring the files below (performed tonight) seem to retrieve their initial version also. (Their initial versions were shown as broken till yesterday).
