This morning I found the ITF down with the RFC not able to relock; I contacted the INJ on-call.
At around 8:30 UTC Piernicola was on site and he was able to fix the problem; the problen occurred at around 5:37 UTC after an unlock when Fmoderr moved the MC FO Z in the wrong direction.
The ITF was then relocked in LN3 at the first attempt (10:14 UTC); the planned ISC started from this point.
At 7:00 UTC the WI chiller stopped to work; the backup chiller was properly put in operation by the "guardian". With Nicola we went in TCS room we reamerd the WI chiller and putting in loop the backup chiller. The WI CO2 laser was not affected by this misbehaviour.
An external firm fixed the problem at the ACS COB.
