Can you confirm the address you withdraw your coins to (coinbase address) was: 1KoP3jrc3YbQJsmGZjhozhfddywqQKh1Hu ?

I assume that is just a deposit address and you don't have the private keys for that address? and coinbase just credits your "account" with a 0.32 deposit right? If so, it is not unusual for those coins to be moved on... you don't control them, as coinbase has the private keys... they control them... and will simply be using them to settle someone else's withdraw/transfer.

If you account has not been credited with the 0.32 btc deposit, that is definitely Coinbase's issue... as you've noted, their support site says that Bitcoin has "degraded performance"... probably means it is just taking a while for them to process all the deposits and assign them to the right accounts... give it a few hours, maybe raise a support ticket if it has been more than 12 (or the status update changes back to normal and your coins still haven't arrived)
