Let me quote a part of our generic terms of service about Force Majeure:
Tibanne Co. Ltd., agents, partners, ICANN, the central registry nor any person involved in the registration will be liable to the customer or any third party for any direct or indirect loss of profits, earnings or business opportunities, damages, expense, or costs resulting directly or indirectly from any failure to perform any obligation or provide service herunder because of any Force Majeure, or governmental acts or directives, strikes, riot or civil commotion, war, hacking, any natural desaster, equipment or facilities shortages which are beeing experienced by providers of telecommunication services generally, or other similar force or condition beyond Tibanne Co. Ltd.s reasonable control.
And another one:
For all services of Tibanne Co. Ltd. liability will be limited to intention and gross negligence.
We had no intention of getting this to happen, and we have followed every industry standard to make this secure. Despite this it happened. We have learnt new things (especially that lots of people want Bitcoin to disappear).
