On February 2, 2018, the website, as well as Android and iOS apps, were offline as the server shut down by its domain registrar Alibaba Cloud due to failure to renew the domain name. Possible financial constraints within AcFun may be related to the shutdown. The official Weibo account of AcFun confirmed the shutdown implicitly but no official statement regarding it had been made. Access for website and apps has been restored as of February 12, ten days after the shutdown.
Website.
The website allows users to upload, view and share videos. The users are able to comment in the comment section or directly put an overlaid comment onto the videos, resulting in more interaction and communication while watching videos.
Controversy.
AcFun has been criticised for its server instability issues, and the shift on both the official and its user group's political stance while losing the focus on ACGN.
