Affected mlp-users-cn30-cn31-tcmr

In the transition from the older 25Gbit switches to newer switches, two blocks of 4 connections were temporarily unavailable due to a peculiarity of the switches where ports are operated in blocks of 4. The removal of an unused cable triggered a disabling of the other ports in the bunch, reseating one of these connections in one case and re-inserting the unused cable fixed the block of ports to start working again.

The affected machines were cn30, cn31, derpy (the homes of most mlp users) and tcmr, the fileserver for most tcm shares.
