Zilliqa not mining?

[1971ECPT]

Hello everyone. I had observed zilliqa mining is not working since around 6 hours ago. 0 hashes on miner, rigel, or gminer, also pools are not found any blocks since 6 hours ago. Even wallet shows 0 coins.  Anyone knows what's happening? Thanks.

EDIT, this post can be deleted:

It was internal trouble, quoted from TW:
