There are really only three possibilities left for France, NATO, and the greater Western World. First, the attacks were known to be impending and were willfully allowed to be carried out with an insidious agenda lined up to fully exploit the public hysteria to follow. Second, the attacks were prodded along by French, US, or other Western or Western-aligned intelligence agencies. Or third, the global spanning surveillance state the West is erecting with the promise of making the world safe at the expense of our freedom has left us both unsafe, and without our freedom.The propaganda does appear to be working to get the Europeans into a W like trance.
A typical "modern" web site loads untold numbers of scripts and other files from dozens of domains, mostly for tracking, A/B testing and other things that the user doesn't want or need. That's what makes the web slow. I don't think HTTP is a particularly nice protocol, but HTTP/2 is taking a bad protocol and making it worse by "optimizing" it, while the real bottleneck is obviously somewhere else.
