Hi, all:
We are doing maintenance on the servers that power this site tomorrow. The maintenance window is 4pm to midnight, your time. During that window, there will be "occasional outages of up to 30 seconds." For most of the maintenance window, however, the site will be functioning normally.
So, if you encounter an error, just go get a cup of tea or something stiffer, if you prefer. By the time you get back, you should be able to hit "refresh" and continue as usual.
See you on the other side!
