Without looking at blocks in 2009 when it was mostly Satoshi mining, the longest times between blocks were:
Block 74637: 2010-08-15 17:02:43
Block 74638: 2010-08-15 23:53:59
Remember, that on average blocks are 10 minutes apart for a given difficulty. You can calculate the chances of having blocks more than 1 hr or less than 1 min apart with the given difficulty perfectly acceptable.
yes, i concur.
i was perhaps just slightly inebriated last night and fell off my chair when a tx didn't confirm, funnily enough though... I had a couple of tx's which did not confirm until after later ones. What might have caused this? I've never seen this happen before. All tx's were sent and received with correct tx fee of 0.0001
BTCsee highlighted tx and compare the timestamps of those around it, which confirmed before it:
