 Wikimedia Labs
 * Labs suffered a brief, partial outage on October 7th due to a presumed out-of-memory failure on a virtualization node. Everything was back up and running after about 30 minutes; Andrew rebalanced instance load to forestall similar such failures.
 * New hardware has been ordered to expand Labs VM capacity. With luck this will be in place within the next month or so.
 * Marc redesigned the default base image for labs instances. /var/log is now in its own partition, and we support some limited partition resizing.
 * Yuvi has made a good start on setting up instance state monitoring.
 * Marc added an Ubuntu Trusty bastion and exec node to Tool Labs. Some work is still in progress here due to package renames and dependency changes.
 * Marc wrote many pages of operator documentation for tool labs.
