can't tell for sure... without constantly surfing a site for hours "hoping"
to get an error... I do, however, occasionally check other sites on the same
server (one using the same library of code), and haven't spotted a problem
yet.

I have access to the logs, but it's a bit tricky -- I have to wait until I
spot an error, then download a 10+meg log, and try and find my request...
but I'll work on that next for sure.
