If it's not her local provider, there may be a relay server that she goes through fairly consistently to get to mudcat - that she doesn't hit going to other places. To tell whether that's the case, we'd have to look at what other sites she goes to.

There might also be a timing factor - if she does quick trips elsewhere but spends more time at the 'cat, or the reverse. Some providers will kick you back to a sort of "standby" if you're inactive for a while, making it necessary, in effect, to re-connect when you do the next click.

It's not very practical to try to do a "long distance" analysis in this kind of detail. This needs to be done by someone who can get "hands-on" (her computer, that is) and can see exactly what she's doing and where she's going.

As mentioned above, the 'cat is pretty consistent about showing you an error page that it sends back when there's a problem, and it's immediately recognizable. The "404 Error" that you get from other sources is such a generic thing that it's not really much help - particularly since it's usually difficult or impossible to tell where it came from.
