We are investigating issues with Zendesk Services in Pod 4 & 8. We will provide an update shortly.
On Saturday, August 6th 2016 our network operations team made a change to increase the capacity of our Load Balancer Tier for Pods 4 & 8. We added 1 more blade to our 2 chassis in the data center to give us more memory and higher availability. We hit a bug that caused a memory leak in the new blade. To fix the issue, we failed over from the bad chassis to a good chassis. To prevent this from happening in the future we have upgraded the software on our chassis and have added better monitoring to alert our network operations teams.
