Yup, Yesterday my transaction took over 9 hours to confirm, i was thinking the same thing, i don't believe this is a usual thing, not sure what happend.
 It also seems it only happens with lower absolute transaction fees, which is probably why it took so long since i was sending a small amount.

Is there going to be any solution for this problem in the future? If transaction confirm times are going to be so long, Bitcoin, as a currency, is going to face a lot of problems, amirite?
