Looks like the site is going to end soon. Its long time since the blockchain resolved there issue that is the last tweet was around 4h ago that service is restored.
yes the blockchain run ok but we traied to restart the api and find that we can't spend the money in the wallet ,api refuse to send btc
( you will see many other in the few hour speaking about the same problem )so we have two solution ,wait that blockchain.info resolve our problem
or move all the wallet to another one with a fresh new address , and reconfiguring the api
in the two case it will take hours
Thanks Admin
