Zendesk will perform necessary maintenance on Pods 5, 6 & 9 on October 22, 2016 between 13:00 and 13:30 UTC. (06:00 - 06:30 PDT)
During this maintenance window, customers may experience a brief period (10-15 minutes) of performance degradation. You may see timeouts or errors while logging into the Zendesk, using the agent interface or when using the Zendesk API.
Retrying the previous operation, or refreshing your browser, should work to clear the errors.
