    Of course your throughput will be limited by existing network load. 
    You can monitor that using our public traffic graphs:<br class="">
    <br class="">
    <a href="http://monitoring.hamwan.net/cacti/" target="_blank" class=""><tt class="">http://monitoring.hamwan.net/cacti/</tt></a><br class="">
    <br class="">
    The login / password is hamwan / hamwan.  (I though I had gotten rid
    of it, but it persists.)  These only update once every 5 minutes, so
    they're not as handy as they could be for manual testing.  In most
    cases though, the network is idle enough that you won't need them,
    and bandwidth-test results will be highly indicative of link speed. 
    Be sure to give the links at least 30 seconds to come up to speed. 
    They default to sitting at a lower speed when they're not being
    asked to move lots of data, and then they train up on higher speeds
    as required.  This is to maximize their reliability when only low
    data rates are required.<br class="">
    <br class="">
    Oh, and you will not be able to do a bandwidth-test to the edge
    routers.  These have firewall rules that prevent bandwidth-testing. 
    We should really fix that at some point.<br class="">
    <br class="">
    Speaking of fixing, I've started writing some software last night to
    help us optimize the QA-CP and QA-Westin links.  Both of these
    sometimes affect your connection.  As Tom mentioned, QA-CP is
    affected by a poor path to the side of a dish, but QA-Westin is
    affected by Amazon constructing a new building right in the signal
    path.  You can view the path obstacle here:<br class="">
    <br class="">
    <tt class=""><a href="http://cam.westin.hamwan.net/" target="_blank" class="">http://cam.westin.hamwan.net/</a></tt><br class="">
    <br class="">
    If we can't get either of these links to perform acceptably, we can
    manually give them a lower priority on the network.  The QA-CP link
    might be helped a lot just by installing a higher gain modem @ QA
    and/or rotating/upgrading the dish @ CP.  The QA-Westin problem is a
    little harder.  So far we've reduced the bandwidth of QA-Westin to
    help it out, and you can see the signal increase in the associated
    graph:<br class="">
    <br class="">
    <tt class=""><a href="http://monitoring.hamwan.net/cacti/graph.php?action=view&local_graph_id=439&rra_id=all" target="_blank" class=""></a><a href="http://monitoring.hamwan.net/cacti/graph.php?action=view&local_graph_id=439&rra_id=all" target="_blank" class="">http://monitoring.hamwan.net/cacti/graph.php?action=view&local_graph_id=439&rra_id=all</a></tt><br class="">
    <br class="">
    But it doesn't seem to have helped speeds at all, so now we need to
    do some interference-avoidance work.  I hope to have that software
    finished this week.<br class="">
    <br class="">
    The last problem we should address here is the apparent route
    flapping inside the network.  We don't have any good tools in place
    to monitor that, and it looks to be affecting your path.  While this
    shouldn't result in outages for you, it does indicate marginal
    network stability, so it's a problem we need to look into.  I do
    have designs to monitor this and mitigate it, but they're slightly
    longer-term.<br class="">
