Well, my SEPA transfer eventually came through during the crash. I had half of my assets in BTC and the other half in EUR at the site (which I have been using for a while previous to a couple of weeks ago without any problems).
I requested a SEPA withdrawal of a fair chunk of money a few hours before everything went tits up.
I'm holding out hope that he'll be able to get this sorted, and would urge people to keep in mind Hanlon's Razor* during these problems…
