HTTP 507 Insufficient Storage is a WebDAV extension (RFC 4918) indicating the server cannot store the representation needed to complete the request. Unlike a disk-full condition (which might be a 500), 507 specifically means the storage quota or allocation for this operation has been exhausted. In modern cloud applications, this could indicate: user storage quota exceeded, database tablespace full, or blob storage limit reached.
Response includes the status code, standard headers (including Content-Type), and a small diagnostic JSON body describing the request and returned status.
