# 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.

## Durability and reliability
