    There is currently a network outage affecting the lower floors of Lerner Hall. Technicians are investigating. We apologize for this service interruption. For a complete list of recent and upcoming scheduled service changes, please visit


    UPDATE: This was resolved on 5/21 11am.  The cause was determined to be a misconfigured non-CUIT router conneced to the network. Once removed and re-configured, the issue abated.

  • Telephony - NetPhone

    From approximately 1:50pm to 2:50pm there were intermittent service denials for Netphone users placing outbound off campus calls. The problem has been identified as 2 of the 7 inter-PBX T1's that pass traffic out to the PSTN. Technicians have removed the faulty T1's from routing to prevent further service disruption while they investigate the root cause.
  • Mass Email
    05/19/2009 - 01:05pm to 07/07/2009 - 01:06pm
    This afternoon, many of our users received the below forged message, which threatens to turn off your email account if you do not send in your password and date of birth.  This is known as "phishing" and is an attempt at identity theft.  This mail did NOT come from CUIT, or anyone authorized to contact our users.

    CUIT will never ask you to send your password or date of birth in email.  We will only ask for this information on secure Columbia web pages.  You should never share your password, and you should never send it in email to anyone.  If you have, you should make sure to change it right away.

    CUIT filters all incoming mail to prevent such phishing attempts from reaching our users.  Sometimes, as in this case, the messages slip  past the filters due to new wording or other changes by the senders.   We are adjusting our filters to prevent any more of this particular attempt from slipping through.

    We are also working to block responses to this message (i.e. users sending their passwords).  We will also track down any users who have responded and assist them in changing their passwords to secure their accounts.

    We are sorry for any confusion this phishing attempt may have caused.

    We're continuing to work with Verizon on restoring the Tie-Line Service.


     CUMC lost all Voice inbound DID & Tie-Line Service.

    This outage affects Voice Tie-Line service between CUMC and Morningside Campus. This outage is due to an electrical panel fire located in the Service Building.
