The block after your transaction was mined within the same minute. Sometimes miners get lucky and multiple blocks get mined in close proximity.

Thanks for the clarification. Tongue

Maybe you find interesting - the chances of that second block being found in 23 seconds or less is about 4%, higher than intuition may lead you to believe:

What is less likely is a transaction with only 0.0001 fee being included in the next block - based on blockspace competition with other fee-paying transactions, that could have taken a long time. Miners like me today.

I just sent .0004 BTC with a .0001 fee to myself, and it has two confirmations within three minutes of hitting send. WTF is going on here?

Just a counterpoint to the "blah blah blockchain.info didn't pay fee why no confirm" threads. Use your own Bitcoin-qt and include a bare minimum fee and you'll probably not wait much.

(same transaction 2 weeks ago, 15 blocks before inclusion though...)
