HTTP Status Codes

507 Insufficient Storage

A WebDAV status meaning the server cannot complete the request because it lacks the storage to hold the representation.

What it means

507 Insufficient Storage (RFC 4918) means the method could not be performed because the server is out of space to store the resource — for instance a WebDAV PUT when the quota or disk is full. It is a server-capacity error.

Why it matters

  • It distinguishes an out-of-space condition from a generic 500, guiding operators to capacity.

Common mistakes

  • Surfacing 500 for what is really a disk/quota-full condition, obscuring the real cause.

How WebInspect checks this

  • WebInspect flags 5xx responses; a 507 indicates a storage-capacity issue on the origin.
