Too Long; Didn't Read
My first attempt to log EC2 instance names to <a href="http://pagerduty.com" target="_blank">PagerDuty</a> and <a href="http://airbrake.io" target="_blank">Airbrake</a> broke most of our infrastructure. I failed to account for unpublished AWS rate limits, and when an unexpected volume of errors caused my code hit those rate limits, insufficient error handling led to an infinite loop when errors were thrown in our exception loggers.
