Info from Machine RC (Lars):

Author: Froehlich

One of the cold compressors has stopped working around 2:00 on Saturday morning due to a problem with the new motor (with magnet bearing). Since no beam operation is possible anyhow, the cryo team and machine coordination have decided to start necessary work on cryo plant stages 3&4 already on the weekend, in parallel to troubleshooting the motor problem.

All XFEL shifts up to Monday 7:00 are canceled. The morning shift on Monday will supervise the already scheduled access for the repair of A16 and, if possible, the restart of the linac.
