The downtime was due to a server crash on Saturday, November 15. I did have backups. However, they were a few days old, so some stories and threads would have been lost.
Because the file system of the server was corrupted, I had to hire a Linux Administrator to restore the data. This lasted a few days. Then I had to install the server environment from scratch. Also, I have taken the opportunity to set up the CDN CloudFlare.
Currently I am planning to upgrade the server environment by adding failover capability. This means that Chyoa will be hosted on a cluster in the future and if a server fails, another jumps in. If everything goes according to plan, failover will be added next weekend.
New features are coming, but so far I was concerned with the restoration of the data.
