Arch Linux官网遭DDoS攻击，暂仅支持IPv6访问

Core Viewpoint - Arch Linux is currently facing a targeted attack on its official website, which requires intervention from its hosting service provider to resolve the issue [1] Group 1: Attack Details - The attack is occurring during the Western Christmas holiday, which limits technical support resources and complicates the resolution process [1] - The estimated time to restore normal service is expected to be longer than usual, with no specific recovery timeline currently available [1] Group 2: Mitigation Measures - To prevent further escalation of the attack, Arch Linux has implemented temporary protective measures by shutting down IPv4 access and retaining only IPv6 access to maintain minimal service availability [1] - This temporary measure has resulted in most users being unable to access the website normally, as IPv4 is still widely used [1] Group 3: Historical Context - Arch Linux previously experienced a large-scale DDoS attack several months ago, which temporarily rendered its user software repository AUR unusable [1] - The project team is actively coordinating resources to expedite the resolution of the current issue [1]
