Servers in the Ukraine
Since when did Ukraine give out online gambling licenses?
I am now wondering whether this is something along the lines of the GoWild problems a while back - the servers being TAKEN down by the Ukranian authorities pending an investigation of their activities. This would explain almost everything, how they could not simply execute a "rollback" to the previous working configuration, why they had no access to their back office and no ability to allow players to withdraw their funds if they didn't want to wait an indefinite length of time for a restoration of service, etc.
GoWild got out of their mess by pulling out of Croatia altogether, and even now the police there don't seem to have closed the case. RevenueJet may have had to move to a different base of operations, which would explain the length of time this has taken, as well as the instability of their return. Things may well return to normal as they did with GoWild, however the true scale of the risks were hidden from players. Had they not been able to restore services, would players have recovered their money.
What backing do they have now? Having been offline for the best part of a month, no revenue to speak of, yet a month's worth of continuing liabilties for staff, hosting, etc; plus an unexpected cost in restoring the service after the screw up, which seems to be a month long technical contract for someone, which doesn't come cheap, and now they are jacking up the risks by offering huge boni to lure players back. If too many of these boni are beaten, they may not be able to pay, and will have to start delaying payments or using "smallprint" on players to mitigate the risk.
