Currently our server hardware is physically located in a data center in Dallas. Over the course of the next 3 days, I will be transitioning the site's hardware over to a new location, also in Dallas.
So as part of this transition, I will be moving the site from place to place and those movements will cause slight delays in service. If, during the next couple days you get a "Site unavailable" type message, that just means that I'm in the middle of a transfer, and you should wait 10 minutes or so and try again.
I expect that the downtime will be minimal, but it will be there. The biggest interruptions will be this afternoon and Saturday afternoon.
