I am using Blockchain.info's integrated chrome wallet.
That's unfortunate. You can't use RBF then. Please consider using local wallets (Core, Electrum, Multibit).
Heck even now the unconfirmed transaction has reached over 35K!
It is an attack on the network.
Guys please do not suggest here for a blocksize increase because that is a useless suggestion for now.
It is useless because: A) We can't implement it quickly and there is no consensus; B) It doesn't solve anything and we'd be dealing with the same problem.
Increased blocksizes might be a good thing after all
It won't solve the problem.
tomorrow it will be 50k
It is an attack so we can't really know.
