Annotations database down; GET still returns 200

The annotations database seems to be down again; the interactive 
interface shows

Cannot connect as "root" to localhost:3306 with 
"DBI:mysql:annotest:localhost:3306"
switching to ephemoral DB

However a GET on annotest.w3.org?w3c_annotates=[url]&w3c_forceText=* 
just returns a 200 status with no annotations included:

<?xml version="1.0"?>
<!-- session-id 1078741083.493782" -->
<r:RDF
  xmlns="http://www.w3.org/1999/xhtml#"
  xmlns:a="http://www.w3.org/2000/10/annotation-ns#"

  xmlns:http="http://www.w3.org/1999/xx/http#"
  xmlns:r="http://www.w3.org/1999/02/22-rdf-syntax-ns#" />

  Would it not make more sense to return some kind of HTTP error code?
