there was scheduled power work in the area of the host department for the archive machine.
the host department had assumed that its ups would cover the period of switch over, but no such luck -- it still hadn't restored itself before 1300 utc, when i stopped monitoring.
the ctan team apologises for this failure, though it was plainly out of our control (i'm no longer a member of the department, even).
