First round of updates went smoothly with no downtime or issues. Tomorrow's update will cause downtime though. Probably 3-4 hours.
Linode, our hosting service, has upgraded their services and in order to take advantage of the upgrades we need to power down our machines. This first phase of this upgrade will occur on Saturday 4/19/2014, and will involve upgrading our frontend and apache clone. This should not require taking the site offline but could potential cause strange behavior or decreased performance.
