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

Also, there seems to be a problem with the timestamp. Take for example the block 2016. The rawdata shows the timestamp 1233063531, which corresponds to 27 Jan 2009 13:13:16, but in the block page you show 2009-01-27 13:38:51.
