ZEC is often under maintenance last time

Hi, guys! Do you know why this week ZEC under maintenance on POLONIEX twice? Is it problem zcash or POLONIEX? Thx.

poloniex is the problem.

Seriously? Or you just think so? Maybe you have some proofs?

polo has a long history of fails… also, kraken’s working fine

If you want proof, do a search of these forum’s and you can read it for yourself.
