I had a batch overcarb overnight last week, so its a good idea to check up on them by feeling the bottle. When its as hard as it was with coke in it, then fridge/pasteurize it!
I've had my first cider in glass bottles & 1 soda bottle for 2 days, and the soda bottle is now rock hard. I thought it would take 5 or 6 days to carb, so this is curious. I popped one of the glass bottles, and it pours with a nice fizz, but the head immediately disappears and it tastes a little flat....although i'm not used to cider. So i'm not sure what to do...probably safer to pasteurise now given how hard the soda bottle is?
