Minexpool works fine. On telegram you can find the pools list. You can contribute by mining elsewhere than suprnova to distribute the hashrate if you are worried.
Minexpool doesn't work fine - I tried it for a month - I had full nights or hours of either site or stratum problems.
This seems normal for you (and I've seen it going down to zero...) ?
https://snag.gy/7QMU4C.jpgI don't have telegram, and probably won't.
I don't know any other pool than minexpool and suprnova.
Usually pools are found in the first post of the discussion...
Somebody is attacking the stratum protocol. Pool owner can probably explain better.
