This evening, November 18, starting around 5:00pm, Amazon began blackholing traffic towards the Sonic network. We attempted to route through a different upstream provider, but it appears the routing issue was too deep into the Amazon network. We believe they have fixed the routing issue, and all traffic has been restored as of 5:25pm.
Update: This issue appears to have re-surfaced. We are reaching out to Amazon to determine the cause of the outage and do everything we can to ensure it does not happen again.
