At 8:30 a.m UTC, we started noticing few application errors due to DNS resolution problems at one of the Availability zones in AWS (US-EAST-1 region). Servers hosted in other availability zones were not affected.

Primary failures were for scheduled jobs. Few api requests that were served from that region were also affected.

Post identification, we immediately disabled serving requests from that availability zone.
