Is the service currently operational?

I noticed that on your site, you currently have this message up:
We're currently experiecing some techincal issues. Service will return to normal shortly. Sorry for any inconvenience caused.

I was trying to test this functionality out, I do not believe I can currently complete a transaction.  When I attempt to "Sign" - nothing happens.  It just sits there - am I doing something wrong?

I was able to create the multi-sig address, and I was able to send a small amount of BTC to this address.  Now I am trying to sign the transaction and release the funds.

Is there an online wallet provider who supports multi-signature transactions?

It looks like blockchain.info used to have an escrow service, but it looks like they no longer offer these services due to lack of use:
https://blockchain.info/wallet/escrow

Do you know if these methods are available through:
https://blockchain.info/api/json_rpc_api

Are there any escrow services out there that can be called via an api to generate a bitcoin address that can be used for multi-signature purposes?
