It appears the http://blog.wordpress.com/wp-admin/ interface has been unavailable since approximately 09:20 PDT. I can't confirm if it's other peoples' blogs or just my own. It's definitely some kind of wordpress.com issue, given that after about 35 seconds (possibly DB query timeout?) I get back the following message from your servers:
There was a small systems error. Please try refreshing the page and if the error is still there drop us a note and let us know.
Here's validation of my 35 second timeout claim, as confirmed by time/curl:
Is anyone else experiencing this, and if so, is anyone administrative looking into it?
The blog I need help with is koitsu.wordpress.com.
