    An issue with TCU’s domain name system Tuesday night caused the second outage this month for the university’s e-mail server, a Technology Resources administrator wrote in an e-mail.

    Bryan Lucas, executive director of Technology Resources, wrote that the DNS issue arose because of the flooding of the university’s server room in Sid W. Richardson Building on Feb. 4, which caused the initial outage in e-mail and wireless internet.

    The e-mail servers were down from approximately 8:30 p.m. until 12:10 a.m. Wednesday, he wrote.

    “We had an issue with the student mail servers and their ability to properly use DNS, which led to them being offline,” Lucas wrote.

    According to the Google Public DNS website, DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book. Every time a user visits a website, their computer performs a DNS lookup. Computers often require hundreds of DNS lookups each day, according to Google.
