Blockchain confirmations are treated according to the bitcoin protocol. The average time for a transaction is about 10 minutes, but that depends on the network"s capacity.
The blockchain is fully decentralized, there is no central authority that controls it, that makes it so secure.
BlockChain.info is a site owned by a UK-based company and provides information about blockchain and web-based bitcoin wallets. So they do not have any control over it either, they only provide a user interface where you can get information about the network.
From a technical point of view, confirmations rely on network miners, including your transaction in the block, they are mining and attaching to the block.
