Experiencing a server error on your 21YunBox site? Here’s how to identify and address the issue effectively.

1. DDoS Mitigation

What is DDoS Mitigation?

DDoS (Distributed Denial of Service) mitigation involves security protocols designed to combat attempts to disrupt normal traffic to your website. At 21YunBox, we manage this along with your developers and CMS provider globally, including in China.

Potential Issue and Solution

While DDoS protection secures your site, it may block significant but legitimate traffic, especially in China.

How you can help: Consider adjusting the rate limit or threshold for DDoS protection.

How 21YunBox can help: Contact us to discuss adjusting the DDoS protection settings to allow more legitimate traffic.
