It's wired that some of sequence block number were missed out in "blockchain.info"
Is it a problem of connecting with nodes or any other meaning behind this. Anyway praying for not a hack and for my bitcoins are safe there.
I am not really understanding but if it is that you hold your bitcoins in blockchain.info wallet then this is really a bad decision from your side. Always use desktop wallets as they offer us better security, they sit on our PC and not on some back end of some website which is not guaranteed they will be online forever. Usually people nowadays keep desktop wallets which offer seeds because of their functionality,security and being very flexible. Multibit HD and Electrum are such wallets.
If this is not what you meant, then I am not understanding.
