Yeah this is messed up. It looks like they are getting DDOSed as the price is crashing hard globally.
If they were DDoSed then their mt4 servers will be offline too but they are online and logging is working fine but trade is stopped.
The owners of BTC-e are Alexei and Alexander, who previously worked in ZhK Skolkovo Park, Moscow.
Maybe information at
