For now it is quite normal. Monero fork probably took 80% hashrate away from the network and difficulty adjustments will take 720. I have not check but i think we are at 200 or so blocks since fork. 720 blocks is normally 1 day. Will take a few days before it normalizes. My guesstimate was 2-3 days. Check blocks page in pool and you will see no blocks been found yet. only 9 blocks in last 24 hrs.
