Service is back to normal in pods 5/6/9. Thanks for your patience.


An uptick in traffic caused by a DDoS attempt on one of our IPs in the East Coast datacenter caused network instability and packet loss. DDoS mitigation was put in place as a safety measure and traffic subsided organically afterwards, resolving the incident. To help prevent this in future, we will review our mitigation thresholds to ensure they are set appropriately.
