Amazon SES service interruptions in US-EAST at around 8:42PM PST

We started noticing some SMTP errors in some of the applications that use SES to send outbound messages with the stack below:-

javax.mail.AuthenticationFailedException: 454 Temporary authentication failure

        at com.sun.mail.smtp.SMTPTransport$Authenticator.authenticate(SMTPTransport.java:892)

        at com.sun.mail.smtp.SMTPTransport.authenticate(SMTPTransport.java:814)

        at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:728)

        at javax.mail.Transport.send0(Transport.java:253)
