Hi Hoagy,
As from today operators need to have a license to offer gambling services to Irland, and pay taxes in Irland.
Apparently Netbet havent got that license yet so thats why they closeing for some time,, how long they will remain closed i cant answer right now.
Alot of countrys in Europe is doing some legislation process lately or will do in near future so yes players from other countrys have been or is effected from changes in their countrys news laws.
