Out of the 149 coins that we currently mine, there are a couple that we have noticed to be slow. Sometimes their individual networks take a bit longer to confirm as they don't mine as often for profitability reasons.

As far as the exchanges, everything seems fine or at least close to normal. A few coins had updates this week which may have caused a pause while they were down, but its necessary to ensure we stay on the right chain at all times. No other changes were made that should effect timing. We'll be monitoring and improving where we can as the markets fluctuate.
