I run my own server with dynamic IP address so it may happen that the server can not be reachable for about max 15 minutes due to the dynamic DNS. The server may also be unreachable when I backup the SSD with Clonzilla (very rarely) or an electrical issue (but this should not happen again). When the server is down, please hang on for 15-30 minutes and the server will be back up.

All my domains (patrikx3.com and corifeus.com) could have errors since I am developing in my free time. However, it is usually stable.
