This morning the first question asked of Oz Linden on the Open Source User Group was; What’s with the restarts? See: Scheduled Maintenance. Oz was all ‘what restarts? Oh… those restarts…’ Saying:
They’re doing some checks on some of our server hardware that requires that they take them down briefly. I don’t believe that all regions will be affected, but I’m not sure.
So, we aren’t really sure what they are checking. It may just be they are giving the gerbils their flu shots.
