The overwhelming majority of the d.o downtime has been from a slammed  
DB server.  For the server side of update(_status?).module, the DB is  
only touched once every 6 hours to regenerate the .xml files for the  
release history for each project.  These queries don't show up in the  
top N list of most expensive queries on the DB server.  To actually  
serve the history, there's no Drupal bootstrap at all, just an ultra- 
thin PHP wrapper.

So, to answer your question: "Yes, we checked.  No, it's not  
responsible at all".
