Remember guys, there’s only one PTR server and it’s hosted in the USA. Blizzard never specify a go-live time for the PTR, but it’s usually mid to late afternoon in the Pacific time-zone. That means, for those of us in Europe, it equates to very late night on the 21st, or the early hours of the morning on the 22nd. For example…
14:00 PDT Thursday = 22:00 BST Thursday = 23:00 CEST Thursday
15:00 PDT Thursday = 23:00 BST Thursday = 00:00 CEST Friday
16:00 PDT Thursday = 00:00 BST Friday = 01:00 CEST Friday
17:00 PDT Thursday = 01:00 BST Friday = 02:00 CEST Friday
