Re: Blockchain.info - Bitcoin Block explorer & Currency Statistics

I was checking your API and I noticed that you only have rawblock information until block 124620. This works: http://blockchain.info//rawblock/124620 and this doesn't: http://blockchain.info//rawblock/124621

124621 is an invalid block index (this is different from a block height)

I thought it was the height, but that wouldn't work. What exactly is the block index?
