Any suggestions as to what might cause a localised problem like this, and how to diagnose it? They have almost zero IT skills which doesn't help at all, but I have tried running a traceroute from my server to their external IP and it hasn't shown any obvious problems. I tried a ping test to look for dropped packets but their external IP isn't responding to ping and there's no way they could change that.
Ask them for a remote login to some desktop sharing app on their computer and ask them to demo the problem to you? Once you have that you can look at what's going on with the server and the client and see if a problem exists. Depending on what you turn up from there you can use that information as the basis for what diagnosis you do going forwards?
