We'll respond shortly.
Our managed hosting provider experienced an extended network outage today, which affected a number of applications including Pivotal Tracker.
The outage was caused by a failure of a primary network load balancer. Network engineers have replaced the load balancer, and are in the process of investigating why traffic did not fail over to a secondary load balancer as expected. They will be performing a fail over test early this morning, from 1am PDT to 3am PDT, during which time some Tracker users may experience increased latency.
We appreciate everyone who notified us about this outage, and apologize for the inconvenience of not being able to access your projects this morning.
