Intermittent 503 Errors for Subset of Users on app.nanonets.com

Incident Report for Nanonets

Resolved

Between 7:19 UTC and 7:29 UTC, a subset of users experienced intermittent 503 errors when accessing app.nanonets.com. A backend node went down and was replaced by a new node. Due to a DNS caching issue, traffic for some users could not be routed to the new node, resulting in failed requests. Other users were unaffected. The issue was identified and resolved by updating the load balancer configuration to ensure proper traffic routing. Preventive measures have been put in place to avoid recurrence.
