[Solved] Not actually my IP, but maybe Blocked

[Computer Nerd Kev]

A user in the US has been unable to access my sites (either computernerdkev.heliohost.org or www.ombertech.com), or open an FTP connection to tommy.heliohost.org, for many weeks.

 

Their ISP assigns them a dynamic IP address, of which one example is: 24.243.100.168

 

All connection attempts time out.

 

They have run traceroute with the following output:

$ traceroute computernerdkev.heliohost.org

This ends at a similar point to where it does if I run traceroute, yet I can access Heliohost fine. So it seems like it's not an issue with routing from the user's ISP - therefore I wonder if their IP address range has been blocked at the Heliohost server for some reason?

Unblocked. They were blocked in the firewall for having 92 connections open to Tommy at the same time.
