Around 3:40pm CDT, we began receiving reports of customers experiencing problems using Zendesk apps. This includes (but is not limited to) connectivity issues, errors displaying information in apps or 502 "Bad Gateway" errors displaying in browser consoles when using Zendesk apps.
This incident has since been resolved.
03:40pm CDT - We are currently investigating reports of customers having issues with Zendesk Apps not connecting or showing error messages.
04:10pm CDT - We are still looking into the details. More updates to come.
04:35pm CDT - We are seeing improvement in the Zendesk app functionality and expect a full resolution shortly.
05:30pm CDT - All-clear. Our developers fixed the issue. Post-mortem to follow here once available.
This incident was caused by a DNS issue on an external partner service, during which DNS requests for a number of domains were not resolving quickly enough. This affected a number of Apps Integrations, causing performance problems mentioned above. Our Operations team pushed a timeout change for DNS resolution. We will be making further changes to how our proxy handles DNS failures to prevent similar incidents going forward.
