The site has been sluggish at times during the past few days, due to our master database running slower than expected. Though the site is still usable, we've prepared a newer, faster master database server that's now standing by.
Late tomorrow night (PST) we plan to swap the servers, which will cause some brief downtime. We'll have more details to post tomorrow afternoon and evening.
We apologize for the lag, but we know exactly what the problem is and it will be fixed soon.
