Whats going on? or is blockchain.info lying?
Here's a second look. yes, there were seven blocks in about a ten minute span recently.
How is that even possible???
Random luck eventually you will see a period coming up where blocks will take half an hour or more to be found to even it out to the 6 per hour again.
It's actually possible that there will never be another block that takes more than 10 minutes. It's just VERY unlikely
The protocol automatically adjusts the difficulty to keep the average time to 6 min. per block, but thanks to the laws of probability and constantly changing network computing power, it's common to see blocks last from seconds to hours.
