Real quick, found out that the Google Analytics plugin, which updated today, totally blows WordPress sites offline. I didn’t realize this until the site had been offline for several hours until I noticed hardly anyone had been on the site all day! I deactivated the plugin and things appear to be back to normal. Sorry for any inconvenience this may have caused.
Edit: They have since put out an update that fixed the problem, apparently this was very widespread, I have seen tons of complaints about it. I wish they’d test things before they put them out!
