Incoming mail to @columbia.edu was subject to numerous delays yesterday because of very high volume. Availability was a very low 90% during 9am-6pm. Mail servers queue and re-try, so all mail was eventually received but in some cases not until evening.
CUIT staff are investigating any possible short-term improvements we can make.
The incoming gateway handles mail from outside CUIT systems to all addresses @columbia.edu. This includes recipients on Lionmail, Exchange, Cubmail, and uni forwarding to other systems.
This same pool also handles mail sent from copier-scanner devices on campus, under the name mx.columbia.edu.
UPDATE: At 3:15pm the problem was resolved, and service has been restored.
Begining at 2:00 PM on Wednesday, November 26, network connectivity became unavailable for the 2nd floor of Lenfest Hall. CUIT administrators have been notified and are currently working to resolve the issue. We apologize for this service interruption.
