10:00am Pacific / 6:00pm GMT – Our monitoring has detected a networking issue within the Amsterdam datacenter that may be impacting message processing within that facility.  That datacenter is used primarily for backup (lower MX priority) traffic, but some primary traffic is also routed through that datacenter.  We are in contact with the networking team at that datacenter, which is working to resolve the issue.  We will post further updates here.  Other datacenters are unaffected.
