Welcome back,
Due to a file system corruption at 01:30 AM Thursday (2014-12-18), the USTC Freeshell Controller server is down for maintainence. We have investigated into this issue and restored the last good backup at 02:00 AM Wednesday (2014-12-17). The good news is, the freeshell control panel is back online since 02:00 AM Saturday (2014-12-20). (That’s the point of this email.)
During this major service corruption, actually your freeshell is still running and can be accessed through IPv6. However, the following components stopped working in the past 48 hours:
- Web control panel (https://freeshell.ustc.edu.cn
</wbr>) - Public endpoints (IPv4 port mapping, including IPv4 SSH)
- HTTP(S) proxy
- Outbound connections from freeshell (fixed on Friday afternoon, a bit earlier)
We sincerely apologize for the inconvenience this service downtime has brought to you in the past 48 hours, which is the longest downtime throughout USTC Freeshell history. We will file a report on this incident on https://servers.blog.ustc.edu.
Should you have any problem with the reborn freeshell system, please feel free to contact us: support (at) freeshell.ustc.edu.cn
Enjoy USTC Freeshell!
