Pottermore.com has officially announced that it HAS
gone off-line for a few hours so that their staff could
smooth out some bugs appearently affecting the site.
The official Pottermore blog, Pottermore Insider, stated:
"We’re aware that some of you are having difficulty
accessing Pottermore right now. Our team is currently
carrying out some maintenance work and, while they make
changes, you may find that the site is temporarily off-line."
They did say, as if to re-assure their viewers that "things should be (restored) soon."
We'll report on this story when Pottermore Insider publishes any new post,
as they promised they would, when Pottermore.com was back on the web.
