Full Description:
Some Cornell email was delayed from 11pm on Wednesday, March 2 until 8am on Thursday, March 3, due to issues with one of Cornell’s email servers. The delay only affected the portion of outgoing and incoming mail that was going through that one server, and all other Cornell email was unaffected. The service was restarted this morning and all queued email was delivered soon after.
