During period 34 there was no single fault which caused 2 or more hours down time. The one think to note are the relatively many small problems due to the various changes (new TCS, new data acquisition computers, new data acquisition programs, etc) that were implemented recently.
The one thing that caused the larger number of faults and down time is a problem with the communication between the data acquisition programs and the new TCS. This is a fundamental problem with the operating system in the new TCS which can not be simply corrected. For most problems a workaround has been made and work on a permanent solution using a different way of communicating is being worked on.
