I hate to say this but Coinbase is starting to look totally sketchy ... I called the Mt. Gox blow up 8 months before it finally happened (in fact I was warning to stay out of it since mid-2011).
There are a number of complaints on the support area of its website. They acknowledged a withdrawal problem for US customers and claim it will soon be resolved. However, there are other unresolved complaints about other problems. I know they say they are insured but after Gox people stopped taking an exchange's word that nothing's wrong.

Some US customers have not yet received USD withdrawals which were expected on or since Friday, May 20th.
We are currently investigating. Please rest assured that all customers will receive their funds.
