The Infrastructure Group
The Infrastructure Group (TIG) provides service-oriented computing, communications and operations assistance to support the world-class research underway at CSAIL. On the technical side, TIG handles everything from maintaining and monitoring a complex computing infrastructure 24 hours a day, 7 days a week to ensuring lab members can access cutting-edge computing services and in-person support. TIG maintains the lab’s four on-premises data centers as well as hosting in off-premises facilities. Additionally, TIG actively promotes CSAIL research to the broader MIT community, reputable news organizations and the general public via a full-range of media relations and communications services.
The network maintenance scheduled for January 2-3 has been completed.
Later in January, a network outage will affect all CSAIL systems in the Holyoke data center — date to be announced.
