Identified

One of our upstream providers in our Phoenix data center is showing some packet loss for ICMP/SNMP traffic and we are following their updates as they address the issue. Customers with monitoring systems traversing this provider may be seeing loss for certain health checks. This does not appear to affect other types of UDP/TCP traffic at this time.
