Dear all,

We are pleased to announce that the Summer 2025 courses will be available for access starting on May 29th, 2025 (Thursday). The enrollment list for each course will be updated continuously from that date. If teachers need to prepare and set up courses in advance, please contact elearn@ntnu.edu.tw. We appreciate your cooperation.

Moodle系統於3月31日 10:30 至 11:15，發生系統連線緩慢問題，經查有來自外部攻擊現象，於調整防火牆規則設定後，已恢復正常。

近期本校部分服務主機及網站經常受到來自外部之短時間大量存取攻擊，若造成不便之處，尚祈諒察。

We would like to inform you that the Moodle system experienced a temporary slowdown between 10:30 and 11:15 on March 31. Upon investigation, we identified signs of external attacks. The issue has been resolved by adjusting firewall rules, and the system has since returned to normal operation.

Recently, some of our university's service hosts and websites have frequently been subjected to short-term, high-volume access attacks from external sources. 

We sincerely apologize for any inconvenience this may have caused and appreciate your understanding.
