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 nature of 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.
