for context: here's a partial view of our outbound error rate over the past 60 hours (this is maybe ~30% of all total mandrill errors): https://puu.sh/CHDxb/729e52451f.png. We see around a 2% failure rate in Mandrill requests on a normal day though, its bad enough we do two immediate retries before allowing our queuing system to start handling retries with backoff.
