Having the same problem, still waiting for the bitcoins I deposited this morning to arrive on my account. Glad to read I'm not the only one having problems. And yes, I saw the red notice, but since it was displayed on the funding/euro page I didn't expect the bitcoin transfer to be down as well.
I filed a ticket too and got the same response about the "high volume of support requests". So I guess I will just wait for the service to come up again now. :-/
Did exactly the same. Saw the notice on fiat and since no warning was on BTC I submitted. When I saw the transaction had over 50 verifications and no coins was in my account I got worried. Had only heard good about Kraken before...
