Just a technical issue, it happens with all sites one time or another. Nothing to worry about
I think the fact that today is weekend made it last longer
When it lasts 8 hours or more in this case or even much less time and no one from the site bothers to communicate with customers via this thread, it always will have the appearance of something more being wrong.
This thread is a way to let customers know what is going on.
All the sites with dedicated threads here should always post promptly when there are problems with their site and people can't get thru.
