The situation was exactly as you suspected. They had momentarily ran out of funds. The coins have moved now.

Thank you for taking the time to reply. The transaction is still "pending" and is only for 9.78 BTC. But maybe you're right, just strikes me as odd that there's not much discussion about this.. I'll update about this situation when there hopefully is something to update.

I tried to send bitcoins from Bitcoin-Central to my bitcoin wallet.

Normally appearing within seconds to my Bitcoin-wallet, now a transaction has been in status "pending" in Bitcoin-Central for 14+ hours. No info of it is in the block chain either. So I suppose the problem is with Bitcoin-Central. Anyone else with similar experiences? I've tried to contact the support but they haven't replied yet.
