Yes, you will need two (2) servers set up to provide your domain name with service before you register.
What kind of obligations/responsibilities must I adhere to when I register a .GL domain name?
Upon declaration, the applicant must sign a waiver that states that the domain name does not infringe on existing copyright law (for trademarks, or the like). 101Domain does not investigate nor does it take responsibility for infringements on the rights of a outside party. All litigation shall be between the owner/user of the domain name. 101Domain is not responsible for the registration or use of the user's domain name.
