I believe there have been times when we've had slight time warps due to issues at our host. I've experienced it too. We've seen episodes when both PMs and posts have disappeared. At times, it has probably only involved a few posts and/or PMs and nobody really notices. Other times, it has involved hours worth of activity and it has been more noticeable. Each of the current problems could have been under such circumstances. Such is the nature of the internet. There's not much we can do about the occasional hiccup. If the problems become more widespread, we can try to research possible solutions.
