[[RESOLVED] Elevated packet loss] Service is operating normally: [RESOLVED] Elevated packet loss
Between 8:48 AM and 11:28 AM PDT, we experienced elevated packet loss within a single Availability Zone (eus2-az1) in the EU-SOUTH-2 Region. This issue resulted in elevated API latencies and error rates for multiple workflows and AWS Services. We were automatically alerted to the issue at 8:54 AM, and immediately began work to identify the root cause while taking multiple parallel paths to mitigate the issue. By 10:00 AM, our mitigation efforts had led to some improvements. By 10:38 AM, we identified the root cause as related to a networking configuration change that we were able to revert the change which led to full mitigation by 11:28 AM. The issue has been resolved and the service is operating normally.
