We are receiving reports of email send delays for some clients using our US datacenter. Our operations team is working to correct this now and expect a fix to be deployed Sunday 11/6/16. Any sends pending processing should not be resent to avoid send duplication. We will post back here with additional details and when the fix is confirmed.
