Yes, that's right. The cluster is currently being rebuilt completely. Until then you have to stick with suprnova (and collect the fractional payouts) or try you luck solo mining and see if that works better for you.
I don't know what hashrate you have, but maybe try the pool for 48 hours and remember the amount of ROI you collected and then try solo mining for 48 hours and compare how many blocks you hit.
The lower your hashrate is, the longer you should make the time frame for comparison, because it could very well be that you cannot find a single block in 48 hours.
