I am working with my hosting provider to schedule a server upgrade in the next few days. I will post again when this happens, but because I'm doing a complete Linux OS upgrade, I will be building out a new server on the new OS version and moving the data there to avoid any issues with an in-place upgrade. This will require some DNS changes and that will take a bit to propagate.
Since we have users in all time zones, this is likely going to happen during the day in the Pacific time zone. I will put the forum into maintenance mode during this time and it will likely be down for a couple of hours.
