The n-Category Café is located at http://golem.ph.utexas.edu/category. We keep this site as a reserve in case anything goes wrong.
The main site will be temporarily down for 48 hours starting at 6pm Central Standard Time on Friday 6 January. In Greenwich Mean Time, that’s midnight at the end of 6 January and the beginning of 7 January. They’re shutting off the power to the building at the University of Texas where the server lives.
