    UPDATE. There have been no outages since these incidents.
     
    The incoming mail gateway for columbia.edu is a pool of 9 servers behind a load balancer. Since Monday 3 hosts in the pool have had outages.

    Remote systems that happened to reach a host when it was not able to accept mail were given a Temporary Fail response, which tells the remote system to try again. The result of this would be a delay in delivery, until the remote system re-tried successfully.

    Some campus hosts including multifunction devices use the same pool of hosts under the name mx.columbia.edu. Some devices showed the error "451 Please try again later" (this is the Temporary Fail response) while other devices just re-tried automatically.

    All of the hosts are up and running properly at this time. The cause of the errors is being investigated.

    06/25/2014 - 05:00am to 06/25/2014 - 08:00am
