What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime.

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
