# August 21, 2024 Service Degradation Investigation
**Date**: 08/21/2024
**Status**: Mitigated
### Summary
A service degradation was detected by our monitoring services between 12:34 PST and 12:48 PST. We removed the impacted servers from rotation restoring full-service. We investigated and solved the issue before bringing the impacted servers back into production rotation.
### Impact
API service degradation in 45-second bursts for a 12 minute period, beginning at 12:34 PST causing some requests to respond with a 502 ‘Bad Gateway’. The issue was limited to a small subset of our production servers, so fewer than 3% of global API requests during this time were affected.
### Root Cause\(s\)
During a routine canary upstream service update, a small number of canary servers became unable to connect to an upstream internal service. Due to this problem, a fraction of requests to these servers caused a connection timeout, resulting in 502 Bad Gateway errors from our proxies.This problem was sporadic, so the proxies did not automatically remove these servers from rotation.
### Resolution
Our internal monitoring systems detected this degradation and we worked to manually remove these servers from production rotation. This restored the API to full health.
After our investigation, we resolved the communication issues with a full code re-deploy and service restart. We then ran a full suite of API health checks, confirmed the problem was resolved, and re-added the servers into production.
### Action Items
We will perform a review of our internal monitoring systems to decrease the time to alert, and review our proxy health-check endpoints to see if they can be improved for partial service degradation.

There was a small outage 10 minute outage due to an unforeseen network issue during a routine deployment.
postmortem
A minor configuration change \(adding an alias to a Redis instance\) caused an unexpected error and prevented the Kickbox app from restarting after deployment. The issue was quickly detected and resolved by the engineering team. The total outage was 11 minutes.
The misconfiguration was identified quickly and a rollback tag was deployed to restore service within minutes.

Just after 11:00 am (central) a routine TLS certificate update caused a misconfiguration. Some users experienced a partial outage.
postmortem
The new SSL cert that was implemented did not support `TLS1.2` . This resulted in issues for only some users where that support was required.
