Human Factors
I was the radar controller working the MGW sector. Aircraft X was en-route at 3;000 feet. The MIA after AIR VOR changes from 3;000 to 3;400 feet a few miles before the CKB approach boundary. I coordinated twice with CKB approach to ensure that Aircraft X could stay at 3;000 feet. CKB approach confirmed this twice. I am still unsure however if I did anything wrong letting Aircraft X fly 400 feet below the MIA for 2-3 miles.I probably should have just climbed Aircraft X to 3;400 feet; just to be safe.
ZOB Center Controller reported an aircraft was 400 feet below the MIA and wasn't sure if he did anything wrong by leaving the aircraft at that altitude.
