We just switched to a new server, as you should know.
To avoid DNS complications we'll be utilizing the IP address for the next few hours to ensure our users DNS servers have had time to correctly resolve to the new server. Resolving sometimes takes 24 hours or more, but its gotten quicker in recent years and months. (My ISP used to take about two or three days to do it, it did it in the time I went to bed and woke back up).
It will be fixed within the next few hours, if kirby hasn't done it already.
