Looks like PressTab abandon HYP, closed coin explorer and sell his own coins.
PIVX daemon is also down, so it's not related to HYP itself. I can't say that we don't need an explorer (though everything transacts smoothly), will try to work on an alternative one.
Cryptopia has been cracking down on coins without working explorers. Lots of them are being delisted last I've checked.
Also harder to get listed on new exchanges without an explorer.
