It is perfectly normal and fine for CloudCoins to become fracked and it only takes a few seconds to fix when the corresponding RAIDA is on line. CloudCoins have 25 unguessable GUIDs (Globally Unique Identifiers) that are stored in the coins themselves. Each RAIDA Cloud verifies one of these GUIDs. If some of the RAIDAs can not verify the authenticity of the coin then the coin is fractured or "fracked" for short.
The system is designed so that most of the RAIDA clouds can be taken off-line and the system will still work. The RAIDA numbers are self-healing so that if a RAIDA misses a transaction, it can be updated with the help of its trusted servers. This means that if a server farm in Taiwan is hit with a meteor, knocking it off-line, another server farm can be created in Australia and the owners of the CloudCoins can update the new RAIDA member with its numbers.
When a CloudCoin does not pass the test of every RAIDA server, we say that it is fractured. CloudCoin software should automatically attempt to repair these but sometimes it will fail. So, CloudCoins may not always have their GUIDs synchronized with all the RAIDA members. In this case they will be fracked. It is up to the person who is taking the CloudCoin to decide if they will accept a lower grade or not. Normally, CloudCoins can be repaired quickly and the fractures can be fixed.
