DO pretty much never seems to post anything on their status page unless it affects a lot of their customers -- I've had support tickets with them where they say a problem is affecting "some" customers, but they pretty much never posted it on their status page. Whereas Linode seems to post status problems far more frequently, and pretty much none of the problems listed have ever affected any of my nodes.

Of course, this is all anecdotal, but Linode really does seem to over report on their status page. And DO perhaps under reports.
