I have 4 figure EUR there I would expect a little more than a Facebook message. Is that so hard to have an error page?! Nevertheless I dont think it is a scam, many met them in person and they have public profiles.
Well, its been down for over 4 hours now. I think this is because the operators live in San Francisco and that is PST so this outage has been between 1am and 5am their time. They should be up in a couple hours and will work it out then I'm sure.
Peace
P.S. nothing on their Facebook page either, pretty sure they are sleeping.
