Tools for ping port announce [News 2009-10-26]
We find that tool port ping some custom port on server can be useful, because it is show time of connection accept that is linked with server loading stats. Usual ping going fine in all cases when network card is alive, and when server freezing - ping continue working. This case of ping will continue going only if software is alive.

Ports scanner tool announce [News 2009-09-28]
We already have tool that can be used for scan limited numbers of ports (scaning going from our server). How we find how to allow our users to scan unlimited (up to 49000) ports of server per one request - it will be very useful for researching security issues of own server, or just find what ports are stay opened during some external (network) or internal (server related) issue.
