They probably won't even know there is a problem until the cms come into work at 7am. They may, however, know by now, but have you ever tried to get IT come to help and put up a system unavailable message?
The only high priority I have is CRT, but I have three MK days to choose from for it, so I think I'll see if ya'll can get through the phone lines first before I wake up my entire family by being on the phone at 7am on a Sat morning.
