Chào cả nhà, mình vừa nhận được thông báo từ bên cung cấp dịch vụ cho TiengNga.net thông báo như sau:

Dear TRINH QUOC VINH,

Currently there is a DDoS (Distributed Denial of Service) attack towards the server with your account.

A DDoS attack is a malicious attempt to bring down the whole server and all websites hosted on it. To do this, the attackers compromise several systems and through them attack a single system, causing denial of service for all websites on the targeted system.

Unfortunately, because of the fact that the attack is distributed (comes from many sources), stopping it is a really complex and time consuming task.

However, SiteGround System Administrators have strict procedures to follow for unfortunate events, such like this one. In our effort to minimize the negative impact on your website and all other websites hosted on the same server, we have taken the following actions:

- We have installed the Arbor Peakflow SP Threat Management System (TMS) solution to protect the server. This is the best DDoS mitigation appliance in the industry.

- Our most experienced system administrators are monitoring the server and all services on it, ensuring the attack does not effect any of the vital services.

- The technicians at our datacenter are closely monitoring the server and all of the inbound and outbound traffic.

Because of the security measures we have taken, you may experience some issues caused by the firewall system in place, due to its' severe firewall rules. The issues might be:

- IMAP interruptions - you might have problems downloading larger emails or listing all of your messages.

- FTP interruptions - your uploads / downloads might fail, especially for bigger files.

- Incomplete HTTP downloads - HTTP downloads may be partial.

- Blocked hosts - in some rare cases remote hosts might be blocked and an user may complain for being unable to access your site.

- cPanel not loading or not functioning properly - in some rare cases, there might be issues loading your cPanel or listing a specific function from your cPanel

The above issues are just temporary and very rare. Please accept our sincere apologies for the inconvenience these issues may cause you. As soon as there is any progress on the case we will post an update here.

Thank you for your understanding and continued support.

Best Regards,

Mình dịch đại ý:
