We have identified the issue as a Denial of Service (DoS) attack, in which multiple devices attempt to overwhelm a website by opening numerous connections within a short timeframe.
Our automated firewall system detected and blocked the offending IP addresses as intended. However, there was a brief delay of approximately five minutes between halting the attack and recycling the connections, which temporarily affected normal website access.
The IP addresses involved in the DoS attack have been blocked, and we have reported them to the relevant third-party data center abuse teams.
We are actively collaborating with our security partners to enhance the speed at which connections are released and recycled, aiming to prevent similar incidents in the future.
We appreciate your patience and understanding and apologise for any inconvenience caused.
