This is one of those just wondering questions. When  you send or receive an email is there a way to see what route it took to get from the start to the finish? My ISP apparently had problems this weekend and I was testing the system by sending myself an email. It took a couple of minutes before it returned to my inbox (repeatedly clicking send/receive). If these bits and bytes travel at the speed of light, it must have had quite the journey. Like I said, just wondering.
