Narrative:

I was supposed to cross cutta intersection at 10000 ft, I crossed at 10700 ft. I was originally on profile to make crossing restr (with no problems), but halfway down, ATC asked us to slow up, which made the restr dicey. I knew that intrinsically, but didn't speak up. I was very tired, 14 hour duty day, and had been riding '30 in 7' all month to get my time in so I could go off on vacation. Captain was off frequency getting ATIS when I was switched from ZOB to pit approach. I told approach we were leveling 10000 ft. They asked if we were descending through 10700 ft and I said yes (we were .4 DME past cutta intersection, doing 4000 FPM descent).
