Since yesterday, website of www.astrill-china.com has been blocked by the GFW, so you can not access this page without using VPN.
But don’t worry, as the Astrill in the router still working fine! Same as the App on phone or computer.
(This is just affect anyone who wanna renew their account or apply a new astrill account.)
Astrill has changed their site for Chinese user in last 5 years twice, till so far, Astrill has not replied the time of the new site up running time for Chinese user yet.
In the meantime, Astrill app still working fine, you may use the App to extend your account on mobile device if you account happened to be expired.
TEK-Shanghai will keep everyone updated.
