I did my time sheet today. 73 hours this work week.
I was woken up on Saturday morning at 8:30am, with a frantic call that started with "$central-mail-switch has failed, we have 1 million messages backed up."
Long story, short version. 6on-6off for 3 days to fix and clear the backlogs. including a full 24 hours of no mail moving. Therefore several of the 6-6s were really 8-4s or 10-2s.
