It’s nothing personal. For much of this morning, they’re going to be moving the database to a new server, and they’re going to shut off write access to it. That means you won’t be able to write comments on any of the articles on scienceblogs for about 3 hours, from 9-12ET today.
This is one step they’re taking to improve performance and make those annoying “internal server errors” and double-posts a thing of the past.
D’oh! Coturnix, who must be more aware of the time than I am, tells me that comments will be off from 9-12pm today. Never underestimate how late a programmer will sleep in; I just assumed 9am was plenty late for someone to get up, have coffee, read the newspaper, write a couple of pages, make a trip to the grocery store, and go in and take care of the lab animals—which was what I got done before 9—and that all that stuff would have been gotten out of the way by lunchtime.
