As many of you are already aware, iMechanica has become quite popular.  As a result of this, the system that hosts iMechanica is experiencing high CPU utilization at various times throughout the day when there are many users accessing the site.  In order to keep the site more stable, I am planning to increase the number of CPUs on the system tonight at 10pm EST.  Please be aware that this will mean the site will be unavailable for about 30 minutes while I am performing the upgrade.  Please let me know if you have any questions about this or if you notice any problems with the site after the upgrade.
