Limits

Storage zone, connection, and rate limits for Bunny Storage, plus the file-renaming limitation.

To ensure optimal performance for all users, Bunny Storage has limits on concurrent connections and uploads.

Connection limits

Limit	Value	Description
Concurrent Connections Per IP	100-200	Up to 200 connections allowed from a single IP address
Concurrent Connections Per Zone	100	Up to 100 concurrent connections allowed to upload to a single zone at the same time
Maximum FTP Connections Per IP	25	Maximum concurrent FTP connections from a single IP address

How limits are applied

Limits are applied on a per-server basis. Each Bunny Storage region runs multiple servers, and each server tracks limits independently.

In practice, this allows you to achieve much higher concurrency than the per-server limits suggest.

Rate limit responses

When you reach a connection limit, further requests will be rejected with:

• HTTP Status Code: 429 (Too Many Requests)
• FTP Response: Connection refused

If this happens:

1. Reduce concurrent connections
2. Implement exponential backoff retry logic
3. Distribute requests across longer time periods

Renaming files

Renaming files or folders directly on Bunny Storage is not currently supported by design, so you won’t see a rename option in the dashboard or over FTP. Allowing renames could cause inconsistencies while content propagates across edge locations, so the action is blocked to keep replication stable.

To rename a file, re-upload it under the new name, then delete the old one once the upload succeeds.
