Update: From Complete Bastard:
EU Referendum blog is down again and it's a big attack. Somebody REALLY doesn't like us. Our host can't do anything about it so we are in the process of moving to another provider (again).Update 2: www.eureferendum.com now appears to be working normally
What is clear is someone is not happy at all. This is a deliberate, and very directed attack - the UGG site appears be acting as cover...
