507 Insufficient Storage
The server cannot complete the request because it is out of storage space.
What it means
HTTP 507 Insufficient Storage is a WebDAV status meaning the server lacks the storage needed to finish the request — usually a write or upload. The operation was understood but cannot be carried out because there is no room to store the result.
When it happens
It happens when a WebDAV upload or copy runs into a full disk or an exceeded storage quota, leaving the server with nowhere to put the new data.
How to fix it
- Free up disk space on the server or raise the storage quota for the account.
- Check whether logs, temporary files, or backups have filled the volume.
- Add storage capacity if the server is genuinely running at its limit.
SEO impact
Damaging while it lasts. A server out of storage can fail to serve pages, and sustained 5xx errors hurt crawling and rankings, so resolve it promptly.
