I just read on their website
http://www.hashprofit.com/en/ (so no https)
Site and infrastructure of Hash Profit is under unprecedented massive DDoS attack right now.
Attackers spreading the word of panic about collapse of our service and other nonsense with only one main target - to provoke mass panic.
Many users neglecting common safety or being inaccurate has compromised their accounts and that has led to availability of malefactors to sell 15% of their hashrate for PFC and sell these coins via the exchange service, which in turn led to downgrade of PFC exchange rate.
All this is happening right now because lead companies of this market has understood the threat from HP service for their place in the market and they're doing everything possible to drown the company.
Right now HP team is working hard to reflect all the types of threats and the most important is defending of keeping and payout system - that's the main target of attackers.
Also our email is overcrowded with spam and rubbish from hacked users' mails, and that makes fast responses to real users questions very hard.
Main help from our service's users in solution of this difficult problem:
Don't panic.
Do everything possible to defend your own accounts - mails, BTC-wallets and computers.
Our service was under the most severe attack ever. Due to most specialists' holidays we've decided for a reliable safety of users' funds to suspend site's work until the first Monday of 2015 (5th of January). Everybody will return to standard work then and we'll continue our work in a usual way. Please be calm. Thank you for understanding.
To keep contact with our users and to separate priority mail from spam, we've developed mail accepting via BTC payments. For guaranteed processing of your message you'll have to pay small amount through an interface below.
We've successfully deflected serious threats and attacks on our service earlier and we're sure that together we can do this even in a situation this hard.
