We are basically down at the moment, as our two database servers had a cascading issue. One went down and took down the other.
Our backup DB server is still up and running, but it's running on slower disks (with more space) and it's currently serving all of our instances and re-syncing the main two DB servers, so whilst that's happening, everything is really slow. It will be another 12 to 18 hours before it all syncs up again.
That being said, the site you are looking at for uptime information seems to be getting confused about our uptime, probably because we use dedicated regional endpoints. Until the DB issues in the last few days, our uptime has solid despite lestat saying otherwise.
