Occam's razor
Every government built website to date either attracts a hundredth of predicted concurrent visitors, or a hundred times it. They either drift on, unloved, or crash under unexpected load. This one had everyone from Obama to Geldof begging people to visit it before it closed and.... it crashed at that point. Gosh. The Russians? Or SNAFU?
Very obviously, SNAFU, and yet our hopelessly Remainiac media once again weave their fake news on top of wishful thinking and pure blind fantasy.
I feel embarrassed for them, to be honest. Leavers are meant to be the thick ones?
