Our Seattle network is currently experiencing major packet loss which is disrupting services. We've alerted our ISP to the issue and are awaiting a reply from them.
UPDATE @ 13:35 BST - We've re-routed the affected prefixes for now so there is no further disruption until the issue is resolved.
UPDATE @ 15:40 - Issue has been resolved and routing has been returned to cnservers. We're awaiting to hear the cause of the issues.
